We have implemented a simple workflow in a SharePoint List. The workflow is configured to triggered on list item creation. The site is consuming a provider hosted app which has logic to create new list items in the above mentioned list. ISSUE: The workflow is not getting triggered if item is created from the SharePoint app. Errors from logs are as below:
"Declarative workflows cannot automatically start if the triggering action was performed by an App-Only request. Canceling workflow auto-start."

"Trusted provider is missing. Provider: '00000003-0000-0ff1-ce00-000000000000'"
