Platform Session inside Rest API extension

Q&A
1

Currently, I am developing an REST API extension. For that, I need to create ‘PlatFormSession’.

I inserted the following code to create the session. But it doesn’t create a session. Throws an exception.

PlatformLoginAPI platformLoginAPI = PlatformAPIAccessor.getPlatformLoginAPI()

PlatformSession session = platformLoginAPI.login("username", "password")

What am I doing wrong here?

See the following exception:

Can you share the exception you get when your REST API extension is executed?

The two lines of code you shared seems valid as long as you includes the proper import statements in your REST API extension class.

See the exception posted with the original question.

Where do you create the Session? In SyncJobDetailsRestAPI or in BonitaUtil?
How and where do you instantiate PlatformAPI?

If you are using PlatformAPIAccessor.getPlatformAPI to get a PlatformAPI object can you test right before the call that session is not null?

If possible sharing your source code can help me to assist you.
