Turns out it is probably an azure portal SWA configuration error. Here is the screenshot of my SWA configuration found on azure portal:


Under API tab, i may have clicked twice in a row the button "Link new Backend". And then the link created twice.

I also couldn't unlink the Function App once it was linked.

After deleting/recreating both the SWA and the Function App, i was able to deploy correctly.
