Error Creating branch to Enterprise GitHub using ABL


New Member
Hi, I'm currently trying to connect to our enterprise GitHub in order to create branches and do some branch merges on an automated way.

Until now, I have succeeded to get lots of things from GitHub (like repos, branches, etc...) using GET method. Communication is working fine and results are consistants.

But in order to create a reference (a branch), according to GitHub API v3 documentation, I have to perform a POST and provide a Json as the entity.
Here is an extract from GitHub API v3 documentation:
Git Refs
as you can see we have to perform a POST request and attach a very simple Json to it (only two fields).

And here a part of my code (credentials are set before in the code and are not involved in the current problem):
mc-request = "".
IF al-credentials-ready
THEN ao-Request = RequestBuilder:post(mc-request,ao-json-request):ContentType("application/json"):UsingBasicAuthentication(ao-credentials):AcceptJson():Request.

I paste here the content of ao-json-request (dumped by the 2nd line above, as debug):

My code used to get a branch details is very close than the extract above and work perfectly, but uses the GET method.

When I execute that, I receive the "422 - Unprocessable entity" response from GitHub and the entity contain only an HTML page showing "What ?", no details on the error.

Any idea of what could cause this problem ?

First of all, your Progress version could be very important.
Secondly, what happens if you POST the JSON using Postman or the like?

I am using OE 11.7 with service pack 3.
If I do it with Postman, it works without any problem and my branch is successfully created. (I have done a copy/paste of the Json content)
