sharepoint REST API for Project Data

Question

We have to consume sharepoint project information using rest API's with the access token generated from a registered app
https://medium.com/@anoopt/accessing-sharepoint-data-using-postman-sharepoint-rest-api-76b70630bcbf

However we are running into below error when getting the product tasks with this URL. (Which works when accessed via browser/cookie access)

https://xxxxxx.sharepoint.com/sites/pwa/\_api/ProjectData/Projects(guid'xxxxxx')/Tasks

{
"odata.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.

Answer 1

To all asking, we are still not able to resolve the issue. We are still hoping someone will answer. But meanwhile, we went on using microsoft flow tool, instead of APIs
