I have an AWS steps function defined using this Serverless plugin with 3 steps (FirstStep -> Worker -> EndStep -> Done):

Answered 2021-May-07 at 12:47Given that you invoke the step function with an object (let's call that A), then a task's...

So you are currently overwriting all content in A with the result of your Worker state (implicitly). If you want to discard the result of your Worker state, you have to specify:

Error: Invalid State Machine Definition: 'SCHEMA_VALIDATION_FAILED: The value for the field 'Date.$' must be a valid JSONPath at /States/Insert Data Dynamodb/Parameters' (Service: AWSStepFunctions; Status Code: 400; Error Code: InvalidDefinition;
below is the corresponding serverless.yaml code.
I tried wrapping the two parameters into encoded json string and passed it as single payload field and it resulted in the same error but when there is only one plain field in the payload this code deployed successfully
Any suggestions on how to pass two parameters?

i am using serverless framework with serverless-step-functions plugin. I want to check any errors in my stepfunction workflow and send this error to sqs queue.
Currently I want to pass all input as message to the queue(MessageBody: $). But if I get the data from the queue, message is $ (dollar sign) and not actual input. How can I send to queue the error message from the previous step?

Answered 2020-Dec-10 at 13:37Looks like you are referencing something called CustomIamRole in your state machine creation but I cannot see it being created anywhere in the yaml file. Either create the role and use it in creation or remove the depends on part.

Currently learning serverless and state machines. When I'm trying to do deployment I'm getting error: TypeError: Cannot read property ‘startsWith’ of undefined.
Below you can find serverless.yml definition which I'm trying to deploy. I can't spot the error I did.
State machine I want is really basic and simple. I want to start it with decision, which will direct to correct lambda, depends on input (all of this manual, semi-manual for now). After lambda completion (no matter which one) will be end.

Install serverless-step-functions
Specify your state machine definition using Amazon States Language in a definition statement in serverless.yml. You can use CloudFormation intrinsic functions such as Ref and Fn::GetAtt to reference Lambda functions, SNS topics, SQS queues and DynamoDB tables declared in the same serverless.yml. Since Ref returns different things (ARN, ID, resource name, etc.) depending on the type of CloudFormation resource, please refer to this page to see whether you need to use Ref or Fn::GetAtt. Alternatively, you can also provide the raw ARN, or SQS queue URL, or DynamoDB table name as a string. If you need to construct the ARN by hand, then we recommend to use the serverless-pseudo-parameters plugin together to make your life easier. In addition, if you want to reference a DynamoDB table managed by an external CloudFormation Stack, as long as that table name is exported as an output from that stack, it can be referenced by importing it using Fn::ImportValue. See the ddbtablestepfunc Step Function definition below for an example. In the example above, notice that we used Fn::GetAtt: [hello, Arn] to get the ARN for the hello function defined earlier. This means you don't have to know how the Serverless framework converts these local names to CloudFormation logical IDs (e.g. hello-world becomes HelloDashworldLambdaFunction). However, if you prefer to work with logical IDs, you can. You can also express the above Fn::GetAtt function as Fn::GetAtt: [HelloLambdaFunction, Arn]. If you're unfamiliar with the convention the Serverless framework uses, then the easiest thing to do is to first run sls package then look in the .serverless folder for the generated CloudFormation template. Here you can find the logical resource names for the functions you want to reference.
