adobe.pdfservices.operation.exception.exceptions.SdkException

WE currently get this exception back from the pdf services api:

adobe.pdfservices.operation.exception.exceptions.SdkException: description =Exception in fetching access token, requestTrackingId=(<class 'adobe.pdfservices.operation.internal.exceptions.OperationException'>, OperationException(), <traceback object at 0x71b988899400>)

Is there some issue on Adobe's end?
