Hi,
What I can see from the log is your presigned POST url for output file is not working. You may not have given necessary access. The request fails while uploading the output file to the location.
The error thrown is
'reason': "HTTPSConnectionPool(host='testamisapp.misa.vn'
, port=443): Max retries exceeded with url: /wesign/api/file-management/api/v2/files/upload-public-adobe(Caused by Protocol
Error ('Connection aborted.', timeout ('The write operation timed out')))"}
For any Photoshop API related questions, please reach out to psdservices@adobe.com or submit a ticket here https://psd-services.zendesk.com/hc/en-us/requests/new for support or feedback.
Thanks
