Unable to overwrite already existing file in SharePoint library using Create file in MS Flow

[tidkeamol]

Hi Team,

I have created a flow to copy files from on premise server(when file is created or modified in folder) using data gateway connector and upload it to specific SharePoint library using create file connector.

Flow is working fine for newly created or modified file but for the already existing files in SharePoint document library flow is failed to upload file and giving below error:

"status": 400,

"message": "A file with the name TestFlowCopy/test61.txt already exists. It was last modified by i:0#.f|membership|testaccount@dom on 11 Dec 2020 03:22:51 -0800.\r\nclientRequestId: xyz \r\nserviceRequestId: xyz"

Ideally it should overwrite the existing file content and create version for the same.

Please help me to find solution for this issue. Reply is appreciated a much.

Thanks,

Hi @tidkeamol 

This behaviour is by design. The work around is check the file exists and delete the current file or rename the existing file.

Thanks

Hi All,

I found a workaround for my issue that I am checking whether the file already exist in the document library or not. If the file is already there then I am using update file function in my Flow else I use create file.

Thanks & Regards,

Simply disable 'Allow Chunking' in create file action settings.
