Envoy Connector Message is not a valid JSON format and Invalid/Missing Token

[obadiahjohnson]

I've created a simple flow triggered when an MS Form is submitted it retrieves the form data and populates Envoy's Create Invites with the form data.

I'm getting the below error message even though the form information populating the Envoy connector is all strings.

{

  "error": {

    "code": 400,

    "source": "flow-apim-msmanaged-na-eastus2-01.azure-apim.net",

    "clientRequestId": "357fa99b-4c70-4fab-858a-ab3248fc8235",

    "message": "The response is not in a JSON format.",

    "innerError": "Token is invalid or missing"

  }

Here's the flow

Have you tried it without supplying a Content-type in the field?  That's an optional field and in this case provides no real benefit.

[obadiahjohnson]

I hadn't but I tried it just now. Interestingly enough I get the exact same error message. 

The Envoy piece comes preloaded with the Content-type so I assumed it was essential to the function but that was a great idea to check.

The next thing I would check is to start checking the fields, especially date fields, to make sure they are in an appropriate format.

Hi @obadiahjohnson ,

Can you check the credentials which you are using to connect to this connector are correct ? Token missing errors suggest that either you did not enter correct credentials or you do not have access. 

Thanks

[obadiahjohnson]

Yes, I've confirmed the connection is valid per the connections section in the flow. I used the login credentials that I have with Envoy.

[obadiahjohnson]

All the fields are string fields except the date field which I also tested as a string instead of the Date value that Forms gives.

I contacted Envoy and they gave me this below message:

Thank you so much for your patience. It appears there's an issue with Power Automate and Envoy, Power Automate actions are currently failing if using an Envoy connection based on Username/Password which is the default connection type. This is being looked into and I'll update you once it has been resolved. Sorry for any inconvenience.

Best,
