Flow works correctly but attachment can't be opened



Please be gentle with me, I'm new to Power Automate and have no coding experience! Somehow I have managed to build a flow that takes input from a form, creates a sharepoint list item and creates an email (routing to the relevant teams). The form includes an upload option for attachments.  I've got the attachments routing into sharepoint and attaching to the email, but when we try to open the attachment we get this message:


I thought there might be a permission issue but neither I or the teams can open the attachment so I don't think its permission related.  The attachment looks perfect in the email:


Does anyone have any ideas?  At the moment, I'm going into the sharepoint list, exporting the attachment and replying to all to submit the attachment as a work around but that can't be a permanent solution.

Can you post a screen shot of your Flow?  That will be a big help to those trying to assist.

Also, check to make sure that the file extension is included in the name of the file that you created.

I've expanded the bits of the flow I think are relevant but if you need to see other bits, let me know

Hi @J_Price


 As @ScottShearer mentioned a screenshot would help.


With reference to your problem it seems there is a problem with File Content.

I did add images as a reply.


If I switch to file content in my flow, the flow fails at the send email stage.


This is what I have in my flow:


This is the message in the run: (it means nothing to me but seems like it thinks there isn't an attachment, but there is)

@J_Price  Add a compose action just above the Append array action and log the 'File Content' do you get content in Compose action.


The error tells me attachment content cannot be null.



Like this:


That gets me the same error message I was getting before.

@J_Price  Very Strange problem. Can you remove the get File content using Path and reconfigure it.. 


From the error it tells me that the 'Attachment Content' is null... Which should not be the case, as your Power Automate solution looks correct.. 



I tried that yesterday 😞 


This might be nothing, but in the code for the file, each one has this: "type":null.  Is this expected or could this be the thing that's causing all the issues?

Hello Team,


Can you please share a screenshot of the GET FILE CONTENT USING PATH action, I want to take a look at this. The issue is really with that action in itself.


I can see you have the Action GET FILE CONTENT USING PATH, but there is no way for you to push the FULL PATH as a dynamic content to this action because in the Flow above i do not see any action that makes this dynamic property available which is Get file (properties only).


The best way to use the GET FILE CONTENT USING PATH action is to first include the GET FILE (properties only) action in the flow which gives as an output a property called Full Path and then use this Full path in GET FILE CONTENT using path action.


So just share the screenshot along and let me check.

I would share it but the changes I made caused the whole flow to fail so I deleted the attachment section and advised the team to manually attach the quote once they'd received the confirmation email.  Could you send me a screenshot of what you mean (I've been using power automate for about 2 weeks and am soooo far out of my depth but learning fast!) and I'll try that tomorrow and share screenshots of that?





Hello Team,


No worries, situations like this can happen.


I only need to check one small thing, how you have configured your Get file content action.


The action highlighted in the image below, can you open it and show me how you have configured it.

Hi, I've recreated it. It looked like this.  The bit that's crossed out is the sharepoint site where the attachments are uploading ok.



Interestingly, the flow won't save with this bit rebuilt.  I'm getting this error now:

Did you find a solution?


I am having a similar problem with my attachments which won't open from the approval email or approval saying it is corrupted - but I can open it directly from the SharePoint folder.


I don't know what the problem is - so would appreciate your help!

Hi Yashkamdar, 


Can you please check my flow. I am having the same problem with it being corrupted.


I tried the get file content using path as you suggested. 




Many thanks!

Hi @J_Price and others,


I also had to same issue, my work around was to create a SharePoint sharing link and send that sharing link in the email.

Hope so this helps.

Bit late response to this topic but I just got the same errros and was looking for a solution as well.

In the end I found out that recreating the "File Content" in the "Append to Array Variable" solved my problem.

Strangly enough it rename itself to "Body" after saving.




I thought maybe handy for others to know when searching for this annoying issue....


The Apply to each loop requires information about the uploaded files to be in JSON format. We can construct an expression get this information into JSON format by "wrapping" the dynamic content for the Upload your file property inside a json function:
