I am creating a custom connector that is connecting to an on-prem system which requires a basic authentication. I keep getting an authentication failure as a response and when I look at the request sent out it looks like it is sending it with the Bearer token instead of the Basic. I have tested the API call in two other REST API programs and the call is working when the authentication has the Basic token. I am wondering why the Power Platform is using the Bearer instead of Basic when I have selected the basic authentication. Like I stated this is an on-prem system and I can't open this system to the internet and have to go through the gateway. Any help on solving this or telling me that it is not possible would be great.
