[sithulinhtut]

I write the workflow for reading the image using google cloud ocr.
I already created the google cloud api.
but still, show the error message.
The error message is as

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.Exception: Error performing OCR: GoogleCloudErrorRunningEngine
