When passing parameters from postman to a talend services, tRestRequest component is receiving null response.

Resolution

Review the schema of the tRestRequest component to ensure the Comment field is appropriately assigned.

In REST API Mapping section, by default, if you leave the Comment field empty, the parameter is considered as a Path parameter.

Cause

There are some parameters missing/misconfiguring in the Comment field of tRestRequest component and you need to define what type of parameter it is in the Comment field of the schema.

Below is a list of supported Comment values:

empty or path corresponds to the default @PathParam,
query corresponds to @QueryParam,
form corresponds to @FormParam,
header corresponds to @HeaderParam.
matrix corresponds to @MatrixParam.
multipart corresponds to the CXF specific @Multipart, representing the request body. It can be used only with POST and PUT HTTP methods.
