Corrupted Attachments in SP folder and on email

Posted on by RB-28111619-0

Hello, I’m encountering an issue in a flow I’m building where I collect images through a group form. When these images are saved to SharePoint, I’m unable to open them as they show a "files not supported" error. I also attempted to send the files via email; while some generate previews successfully, others appear to be corrupt.

Literally spent 2 days and counting now trying to figure out. Any insights or guidance would be greatly appreciated. Thank you in advance!

PS: I'm a rookie in Power Automate

@EKarim in the link you shared, I saw you added a compose action. Could you pls share what's inside this action?

Hi @RB-28111619-0

Sorry, that compose action is not needed for the flow. I used it to display some debug info to ensure the flow worked correctly when writing the blog. I've removed it to avoid confusion:

I used this in my array variable and it seems to be working.

{
"Name": "@{concat(items('Apply_to_each')?['name'], '.', items('Apply_to_each')?['fileExtension'])}",
"ContentBytes": {
"$content-type": "@{body('Get_file_content_using_path')?['$content-type']}",
"$content": "@{body('Get_file_content_using_path')?['$content']}"
}
}

Please check the following:

Sometimes attachments just won't open. If this case, you may need to enter the following expressions for the “contentBytes” property:

{ "name": items('Apply_to_each')?['name'], "contentBytes": { "$content-type": body('Get_file_content_using_path')?['$content-type'], "$content": body('Get_file_content_using_path')?['$content'] } }
