[Custom Connector] Custom Connector Operation didn't send Header Authorization to service

Question

Hi Everyone,

I created a custom connector in Power Automate with OAuth2.0 and the connection was created successfully with OAuth2.

But in the action, the requestion didn't send with Authorization in the Header.

We tracked the request in Wireshark, the header includes: x-ms-client-session-id, origin, Accept-Encoding, x-ms-gateway-object-id, etc...

But we cannot find the Authorization header.

Will anyone have idea about it?

Best Regards

David.
