QUESTION
Since a few days, AWS Lambdas can be exposed as web services directly without an API Gateway.
This works fine when setting up through the UI console, but I can’t seem to get it done with Cloudformation, because the resource policy is not attached with AuthType: NONE. And without the policy, I get "message": "Forbidden" from AWS when trying to access the Lambda through the function url.
My Lambda is the following:
...ANSWER
Answered 2022-Apr-09 at 08:35Your template is missing AWS::Lambda::Permission, thus its does not work. You already know what the permissions should be based on AWS console inspection, so you have to recreate those permissions using AWS::Lambda::Permission. This allows you to specify FunctionUrlAuthType.
QUESTION
I'm performing a simple table Scan to get all items from my DynamoDB table, products. Here is the whole Lambda:
ANSWER
Answered 2022-Apr-03 at 18:40Scanning the table returns the map of items and you want to convert map into the struct so in order to convert the list of maps to the struct you want to use attributevalue.UnmarshalListOfMaps under aws-sdk-go-v2. In the previous version it was in the dynamodbattribute but they decided to change the package in the v2.

QUESTION
I'm trying to use CDK and CodePipeline to build and deploy a React application to S3. After the CodePipeline phase, in my own stack, I defined the S3 bucket like this:
ANSWER
Answered 2022-Jan-28 at 07:51For the first question:
And if I change to Source.asset("./build") I get the error: ... Why is it searching for the build directory on my machine?
This is happening when you run cdk synth locally. Remember, cdk synth will always reference the file system where this command is run. Locally it will be your machine, in the pipeline it will be in the container or environment that is being used by AWS CodePipeline.
Dig a little deeper into BucketDeployment
But also, there is some interesting things that happen here that could be helpful. BucketDeployment doesn't just pull from the source you reference in BucketDeployment.sources and upload it to the bucket you specify in BucketDeployment.destinationBucket. According to the BucketDeployment docs the assets are uploaded to an intermediary bucket and then later merged to your bucket. This matters because it will explain your error received Error: Cannot find asset at C:\Users\pupeno\Code\ww3fe\build because when you run cdk synth it will expect the dir ./build as stated in Source.asset("./build") to exist.
This gets really interesting when trying to use a CodePipeline to build and deploy a single page app like React in your case. By default, CodePipeline will execute a Source step, followed a Synth step, then any of the waves or stages you add after. Adding a wave that builds your react app won't work right away because we now see that the output directory of building you react app is needed during the Synth step because of how BucketDeployment works. We need to be able to have the order be Source -> Build -> Synth -> Deploy. As found in this question, we can control the order of the steps by using inputs and outputs. CodePipeline will order the steps to ensure input/output dependencies are met. So we need the have our Synth step use the Build's output as its input.
Concerns with the currently defined pipeline
I believe that your current pipeline is missing a CodeBuildStep that would bundle your react app and output it to the directory that you specified in BucketDeployment.sources. We also need to set the inputs to order these actions correctly. Below are some updates to the pipeline definition, though some changes may need to be made to have the correct file paths. Also, set BucketDeployment.sources to the dir where your app bundle is written to.

I am using Gradle 7.3.3 to build a Spring Boot Application that uses jooq to generate Table, POJO, and Record Classes from a pre-existing database schema. When attempting to upgrade jooqVersion from 3.15.5 to 3.16.0, :generateJooq returns the following error:

QUESTION
I have the following AWS CDK pipeline which works. It basically takes source from 2 different GitHub repositories (one for the application code, one for the cdk code) and builds the application code and the cdk code :
...ANSWER
Answered 2022-Feb-04 at 15:36So I found a solution. Maybe not the solution. Indeed, this seems quite convoluted ... and I am sure there is a better way.
So the solution lies in the fact that the ShellStep in the CodePipeline construct attaches the output of additionalInputs (so the result of the previous CodeBuildStep i.e. lambdaBuildStep) in a specific directory which is dynamically generated but stored in an environment variable called CODEBUILD_SRC_DIR_BuildLambda_lambda_repo so you can see it's a combination of the name of the CodeBuildStep and the repo (with the dash changed to underscores).
So my solution was to use this environment variables as my Lambda code asset.
QUESTION
We're using middy-ssm to fetch & cache SSM parameter values during lambda initialization. We ran into a situation where the execution role of the lambda did not have access to perform SSM::GetParameters on the path that it attempted to fetch. We updated a policy on the role to allow access, but it appeared like the lambda function never picked up the changes to permissions, but instead kept failing due to missing permissions until the end of the lifecycle (closer to 1 hour as requests kept on coming to it).
I then did a test where I fetched parameters using both the aws-lambda SDK directly and middy-ssm. Initially the lambda role didn't have permissions and both methods failed. We updated the policy and after a couple of minutes, the code that used the SDK was able to retrieve the parameter, but the middy middleware kept failing.
I tried to interpret the implementation of middy-ssm to figure out if the error result is somehow cached or what is going on there, but couldn't really pinpoint the issue. Any insight and/or suggestions how to overcome this are welcome! Thanks!

QUESTION
I'm using the Azure Toolkit for AWS to create my lambda, and then running some powershell scripts to act on it. After creation, I get the function's ARN as an output. I don't see anywhere in the documentation where I can access the function via the ARN, everything takes the function-name as a parameter.
ANSWER
Answered 2021-Dec-22 at 19:42You can use the ARN in the --function-name parameter when executing AWS CLI calls for the AWS lambda API.
Here's an example for the get-function api:
--function-name (string)
QUESTION
I have been getting the following error in my CodeBuild execution:
ModuleNotFoundError: No module named 'cfn_tools'
Interesting note, the first time I ran this through CodeBuild with this module I had no issues. It only started happening after I made my next gitHub push that kicked off my pipeline that I saw this. The files that are related to this didn't change, and the modifications in that next push were to an unrelated section of the repo.
I have since tried to do:
pip install cfn-tools&pip3 install cfn-toolswhich mentioned that the module was already installed. These were added to the BuildSpec section. No success - still got the error- I've added a requirements.txt file with no success still got the error. I created this file using
pip freezealso within the BuildSpec. The module shows up, but still get the error. - Originally used runtime version 3.7 of python and then tried with 3.9 which still didn't work.
python runtime 3.9 Any assistance would be appreciated.
UPDATE: To add more information I download a .tar.gz file from S3 that contains the python scripts I need for running in this build. I extract the .tar.gz then I run the script that is having the error. Here is the output for when I install cfn-tools and do a pip freeze You will see below that cfn-tools loads and is part of the output of pip freeze but yet when I run my script it give me the above error.
...ANSWER
Answered 2021-Dec-20 at 19:11The module I was trying to install wasn't the one that was being used.
The module that needed to be installed was cfn_flip it has the cfn_tools module that the code was trying to use. The CodeBuild didn't have it installed, so how it worked on the first run is still a mystery.
QUESTION
There are 3 types of metadata CDK is writing to CFN. Version, Path, and Assets. There's documentation on how to disable version metatadata and it works fine, but i'm struggling with the rest. CLI options --path-metadata false --asset-metadata false work fine, but are kind of annoying.
I've been through CDK Source code trying to figure out key words to plug into cdk.json, but they are ignored. The following is verbose cdk output where it reads my settings and seems to ignore the 2 i care about.
...ANSWER
Answered 2021-Dec-07 at 23:24Looking at the CDK source code, it seems as if the CLI options are currently the only viable option.
