Hi, I have encountered this error while publishing info form list in SharePoint online library has checked all documents there is no duplicity or network issue. Help me to resolve this Thanks in Advance.
Did the issue only occur in one form library?
To troubleshoot the issue, check things below:
Create a new form library in the SharePoint online site and then publish the form to the form library to check if the same issue will occur.
Login to the SharePoint online site with the current user to check if the user has the permission in the SharePoint online site.
Clear IE cache.
Create a new InfoPath form and publish to a new form library to check if the same will occur.
Check if the Desktop Experience is enabled on the server which install the InfoPath. Go to Server Manager and start Add Roles and Features wizard to check. For more detailed information, refer to the article below.
You could submit a service request for the issue in Admin Center.
