API and Webhooks

Trying to create a Custom Connector using Microsoft Power Automate. When I test the Meeting Status operator, I get the below error.

Error:

Thanks for your response Tommy. Here is some additional information. Please let me know if you need anything else.

Link to download the Microsoft Connector we created. Very simple to start.

Hey @JRoss,

I suggest reaching out to Microsoft or googling the issue “Cors error when calling api in Microsoft power automate” as this issue is on their end.

Thanks,
Tommy

I faced the same issue and read the following post: https://powerusers.microsoft.com/t5/Connecting-To-Data/Custom-connector-Oauth-problem-CORS/m-p/504548#M8062

Apparently the error on custom connector setup can be ignored as the action runs fine on MS Flow.

I spent quite a lot of time debugging that just to only find out the connector runs fine regardless.
