after fixing correct project id, as shown in developer console -> Prediction endpoint

Detail="Permission 'documentai.processors.processOnline' denied on resource 
'//documentai.googleapis.com/projects/8xxxxxxxx7/locations/us/processors/axxxxxxxxxx1f' (or it may not exist)."

Adding Document AI Role to service account

final fix

Answer 1

Since @anand (OP) has already fixed the first issue as mentioned on the above updated question, OP got the below recent error

RpcException: Status(StatusCode="PermissionDenied", Detail="Permission 'documentai.processors.processOnline' denied on resource 
'//documentai.googleapis.com/projects/xxxx/locations/us/processors/xxxxxx' (or it may not exist)."

This error is related on the permission of the service account being used to authenticate the API.

You may update your Serivce Account permission by navigating to IAM & Admin > IAM

You may navigate on the list and edit the permission of your service account from that page. You may follow this documentation on how to setup service account authentication for Document AI.

Since your error message shows that you are having issues on documentai.processors.processOnline , you may grant the Cloud DocumentAI API User role to your service account since it has below permissions which also covered the one on your error message:

documentai.operations.getLegacy , documentai.processors.processOnline , documentai.processors.processBatch .

You may also refer to this Document AI IAM Roles Documentation for more information on the pre-defined roles for Document AI.
