We upgraded from AR2020.2 SE to AR2020.3.1 SE (We unistalled all of 2020.2 SE before updating to 2020.3.1 as we have been caught before by upgrades not working properly if you do not unistall previous releases).
Now when we go to connect to the URI published by the API, the API returns an "Internal Error 500".
We have spent 3 days trying to get help on this error but have not heard from anyone at MYOB with expertise in this area.
While waiting for a response from MYOB I thought i would post what actions I have done to try and get around this issue.
I uninstalled AR2020.3.1 SE API and reinstalled it. Then ran the PointOfSale program, PBSAPOS again and attempted an export. ==> Same error.
I then uninstalled AR2020.3.1 SE totally and then restarted the server. (MS Server Essentials 2016). This server only runs MYOB. I installed AR2020.3.1 SE and also the API connector and again attempted an export. ==> Same error.
I uninstalled the API and installed the 2020.2 API and again attempted an export. ==> Got further this time but got the error that the company file was the wrong version. This is correct as our compay file has already been upgraded to 2020.3.1.
I uninstalled all AR, rebooted the server, re-installed AR2020.3.1 SE and rebooted the server and again attempted an export. ==> Same error.
Obviously, the problem is in the API. So where are the patches for this API.
I have attached a WireShark capture of the attempted transaction between PBSAPOS and the API.
It clearly shows "Internal Server Error: 500"
