Trigger Failed - The template language function 'ListCallbackUrl' is not supported

(0) ShareShare
ReportReport
Posted on by Microsoft Employee

Hi,

 

I've created a connector with a webHook trigger, when I try to use it in a flow I get the following error:

 

Unable to process template language expressions for trigger 'Document_Uploaded' at line '1' and column '5077': 'The template language function 'ListCallbackUrl' is not supported by triggers of type 'ApiConnection'.'.

 

Can you help me? In attachment the screenshots.

    Hi NicoAlbano,

     

    What your current situation? Are you still having the issue now?


    From the error message, it seems that you swagger file has something that is not supported.


    Could you check the Swagger file on your side?


    If possible, please share the swagger file for a further investigation.

     

    Best regards,
