DOCR image upload failures can be difficult to diagnose. We recommend attempting to upload the image again to see if it resolves the issue.
If reuploading the image does not resolve the issue, you can troubleshoot further by navigating to your App’s Overview page in the control panel. From the overview page, click the Activity tab and click the deployment link for the latest deployment This opens the deployment’s build and run time logs.
Select the logs for the component that failed and review them for any errors that may help diagnose the problem.
