Hi,
I created a canvas app and on it when I tried to submit the form with attaching file (5 MB), sometimes it is uploading fine in sharepoint list and sometimes not.
I searches for solution for this issue but no luck. Could anyone please help me on that.
Thanks,
HI @panand99 ,
Could you please share a bit more about your scenario?
Do you mean that Attachments control within your Edit form could not upload files whose size is 5 MB in your app?
The user @Beat has faced same issue with you, please check the response within the following thread:
https://powerusers.microsoft.com/t5/General-Discussion/HELP-Attachments-are-not-always-saved-to-SharePoint-List/m-p/252050
The uploading process of Attachments control would be effected by the Network. If your Network is not in a good condition, when your app upload fies from the Attachments control, it may face a Time-out error (which could not captured within your app).
Please make sure that your Network is in a good condition, then try it again, check if the issue is solved.
Best regards,
Try disabling all Power Automate Flow or SharePoint workflows 2013 before performing the patch.
The issue arises because the SharePoint list record is being occupied by a flow. Check if you have workflows, especially those triggered by 'when an item is modified.' If the flow is making adjustments to the record, attachments may not be fully saved in the record. It's best to configure the flows to run after the patch and not use the 'when an item is modified' trigger.
