Purchase requisition WF - Value cannot be null. Parameter name: endpoint message starting workflow

Posted on by Pedro-Rodriguez 270
Hi,
 
I am testing the purchase requisition workflow at a Cloud Hosted Maschine that was restored from a production DB.
 
The WF worked without problems at a Sandbox machine but at this machine I get the following error when I try to submit the workflow for approve:
 
Value cannot be null. Parameter name: endpoint
 
What this could be? It looks like some Business Action (I checked and I have nothing active in this machine), or Dual-Write or whatever else...the error is not very informative.
 
10.0.36 Cloud Hosted
At a Sandbox Machine I did not have the problem
I have the same question (0)

    Hi Pedro,
     
    As you mentioned, the error message is not helpful. I would suggest a developer take a look at it using the debugger. Probably, this will bring you to a root cause. 
    Is the cloud-hosted environment running on the same tenant as the production instance? Did you follow also all the steps for moving a production database to a development environment?

    Hi Pedro,
     
    Kindly check the endpoints for the service and verify.

    Our Microsoft Partner found the problem. The problem was that the parameter "Tax calculation parameters" was activated at Tax, Setup, Tax Configuration, Tax calculation parameters. Tier-1 machines does not support the functionality, then so we had the error at this Cloud Hosted Machine after restoring data from production.
