Unable to get PWA projects using rest APIs

Question

I want to get sharepoint project information using rest API's with the access token generated from a registered app.
However we are running into below error when getting the projects in postman with below URL. (Which works in browser(after login) when accessed via cookie access)

Url - https://xxxxxx.sharepoint.com/sites/pwa/\_api/ProjectData/\[en-us\]/Projects?format=json

Headers - Authorization - Bearer xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Accept - application/json;odata=verbose
Response -

{
"error": {
"code": "-1, System.InvalidOperationException",
"message": {
"lang": "en-US",
"value": "User:<customercontent></customercontent> not found in Active directory or in project db."
}
}
}
Any help to get past this error would be greatly appriciated.

Have you ever found a solution or workaround for this? I've been trying for weeks. I'll go crazy if I can't make it work soon...

I posted on every Microsoft forum and they've just been redirecting me everywhere.
