Having trouble authenticating with App Store Connect

[donnywdavis]

I was trying to give this package a try over the one that we are currently using, but I cannot seem to get the credentials to authenticate. No matter what I try I get an invalidJWT error. However, the key works on another ASC package that we are currently using. I've created multiple new keys, just for this package, using app manager and admin permissions and both get the same invalidJWT error.

I have tried using just the content in the .p8 between the -----BEGIN PRIVATE KEY----- and -----END PRIVATE KEY----- tags, as well as included those. I thought that it might be do to line breaks in the key, so I removed all line breaks. But that didn't work. I have also tried to encode the entire .p8 file to a base64 string with no luck.

Any recommendations on what I might be doing wrong? 🤔
