A little description of the flow: I have a flow that is making an HTTP call to a REST Webservice. There are a couple of errors that we get as statusCode=500 but with different "errorCodes" inside the response body. This request connector is wrapped inside a try block with multiple on-error-continue based on the content of the response body in its "when" attribute. eg: error.errorMessage.payload.errorCode==CODE_A. Adding an image and source code of the flow below

In my flow in Mule 4 I am trying to query a database for specific data. For example I want to run a query like this:

I have a request coming as below format

I am doing a data transformation in Mule 3. I am updating an existing code where a lot of variables are declared inside the DataWeave 1.0

I want to add a field called "type__c" inside a declared variable.

my input payload is as below

I am using scatter-gather to call many endpoints with the same host and different paths. How can I add the HTTP request connector inside For Each scope, that can loop into the different paths and add the payload to the same file?

My code is as below, I would like to loop over the HTTP request;

I'm trying to concatenate the filename and dateTime inside the file connector as name for the output file. I get a syntax error. This because MEL expressions already appear enclosed in double quotes in configuration files, so I have to escape the double quotes with single quotes or \u0027expression\u0027 or "("expression"). How ever none of them works.

The output file should have the following pattern: filename-2020-02-09T12:08:53Z.json

I have tried with this function, only escaping the quotes gives an error

I want to set a variable based on the output in Mule 3.

For example the check I want to do is if there is any payload I want to set the var value to this ${http.path.one} else ${http.path.two}. In Mule 4 it can be done in multiple ways but in Mule 3 seems little tricky. Anyone an Idea?

Thanks

In my case, I'm doing a migration from Mule 3 to Mule 4.

In Mule 4, xpr files are not supported for xml transformation.

So I converted the xpr file to dataweave 2.0.

Most of the logic was solved,but i don't know how to updated the DTOSteps value and DTOCoverage.@FullTermAmt = fullTermAmts.

My Mule 4 Application:https://github.com/Manikandan99/XPR_conversion/tree/master/xpr_validation

Input xml Request: https://github.com/Manikandan99/XPR_conversion/blob/master/xml_request.xml

Expected output xml response: https://github.com/Manikandan99/XPR_conversion/blob/master/responseCISGExposure.xpr

I've defined all the variables in the Mule 4 application.

Stackoverflow not allow me to post many lines of code, so i provided the github links. please go through it.

Please help me to solve it.

I'm trying to convert the below dataweave from 1.0 to 2.0, but everything I've tried gives the following errors like evaluating-expression Error, Invalid input "reduce" and replace.
