Add Release with REST API?

Hi Spira Team,

I was trying to add a release using the REST API, however I was running into issues.

I am able to run some POSTS like the projects/{project_id}/releases/search?number_rows={number_rows}&start_row={start_row}, so I think we have the right credentials.

However, for some reason I was not able to get the create release endpoint working: projects/{project_id}/releases
https://api.inflectra.com/Spira/Services/v5_0/RestServiceOperation.aspx?uri=projects%2f%7bproject_id%7d%2freleases&method=POST

My guess is that I am not putting the correct request data?  I am unsure which data is the required fields.

I tried the following as request data:

{"OwnerId":33,"CreatorId":33,"ProjectId":12,"ReleaseStatusId":1,"ReleaseTypeId":4,"VersionNumber":"7.2.x","Name":"Release 7.2.x"}

Here's the error I am getting in the response:

      <p>The server encountered an error processing the request. The exception message is 'An error occurred while updating the entries. See the inner exception for details.'. See server logs for more details. The exception stack trace is: </p>

Does this error look familiar?  What fields may I be missing in order to successfully create a release?

Please let me know when you have a chance.  Thanks!
