Post Web API with Write to Data Store Entity and Start Process

 Hi All,

I have a scenario where we have a POST Web API to be created which does the following

1. Write to Data Store Entity and send the Primary key as the response

2. Start a process by passing primary key as a parameter

Hence we are trying to make use of a!writeToDataStoreEntity to store value in a local variable and use a!startProcess by passing the stored variable as a parameter and then return a response.

As per https://docs.appian.com/suite/help/18.3/Web_API_Tutorial_-_Level_II.html, we are able to make use of 

a!toJson(fv!storedValues)

However when I try to do a!save() within onSuccess/onError within a!writeToDataStoreEntity it doesn't store any value even when I try to save a simple boolean value. There is no error logged in design_errors.csv as well. As per documentation for a!writeToDataStoreEntity, it could accommodate a list of a!save() or a a!httpResponse() in its onSuccess/onError. 

Has anyone else faced this issue? Any suggestions would be helpful.

Many Thanks,

Arjun
