Custom Connector works in Flow(Power Automate) but not in my Canvas App

[christ15]

When I try to connect to my custom connector in my Canvas App I get following error:

No wadlUrl is specified for this Api. This usually indicates there was an error when converting the Swagger associated with this api to a WADL file.
apiId: /providers/microsoft.powerapps/apis/shared_dcp-20connector-5fdb046ae104b911f3-5f08d8aa3ba56bbd00

Session ID: 99642109-832b-4cb6-bf19-3b8e1c2304b6

The custom connector works well in my Microsoft Flow ( Power Automate) and there are no errors if I open the swagger editor.

thx for your help.

Hi @christ15 ,

Please check if your custom connector is connected correctly under PowerApps site > Data > Custom Connectors:

It is.

I got now the info from Microsoft that dynamic values, which I use in my custom connector, are supported in Flow but not in Canvas Apps.

I have seen people mention that things are not supported by PowerApps or not supported by Canvas Apps. Is there a list of things not supported that wouldn't throw an error in the Swagger editor but will not work when trying to put the connector in an app?

Same problem, but even if I don't use dynamic values, it doesn't work.

Power automate will simply provide you with the output of the API.

Power Apps insists you the define the response given to the API action. No idea why it can't/won't do that dynamically.

But you need to add a default response for you action in the '3. Definition' part of the custom connector editor GUI.
You can just past the output of the '5. Test' response body in the Import from Sample.
