Custom Connector that Calls CalculateRollupField function fails to save

(0) ShareShare
ReportReport
Posted on by

Hello, 

 

I have built a custom connector that executes the CalculateRollupField function on demand for a given Rollup field in an entity inside a Dynamics Instance. I set up the app registration as well. Testing the connector itself works just fine. However, whenever I try to use this connector in Power Automate I get Flow Checker errors, it won't allow me to save my Power Automate flow. 

 

The message I get is 'Invalid Expressions for the input parameters of operation 'calculaterollupfield'" I read on some forums that it might have to do with the @ being used at the variable level of the connector; however I can't remove the @ because then the query would not work.

 

Any ideas on how to work around this? I can't use HTTP connectors because they are blocked by Organizational Policies.
