PDF From Google Drive to Outlook Draft

[J_Oppus]

Hey Everyone,
I haven’t been able to find a way to upload a pdf from Google Drive to Outlook as an attachment to a draft email. I have done both downloaded the PDF from Google Drive and also a HTTP request. I have been getting errors about the Binary Data.

Relatively new, so a step by step would be most helpful.

Thanks

Are you trying to use the PDF binary as an attachment on the outlook draft, or as the message content?

Hi,
I noticed a couple of things from the screenshots. Please try the following steps:

1- In the HTTP node, set the Response Format to File.

2- In the Outlook node, add Attachments.

Click Add Field, choose Attachment, and put the binary “data” in that instead of in the “message” field.

This is what I get as an error code.

1- In the HTTP node, set the Response Format to File.

I have already. It still gives me the “were unable to deserialize” error code on the outlook end

.

[mohamed3nan]

Wait, why are you using the HTTP node? If you want to download a file from Google Drive, why not use the Google Drive node with Download Operation?!

and Options Output File: data
so this will be the input for the outlook attachment

[J_Oppus]

Okay I did that now but when it gives me the error code “cannot deserialize”

[mohamed3nan]

hmm
at this point I think this is a bug since you’re using n8n cloud and according to:

Outlook NodeApiError: were unable to deserialize

Hello everyone, I’m currently facing an issue when posting a message on n8n (cloud version) and adding an attachment to Outlook (also cloud version). I’m encountering a “NodeApiError: were unable to deserialize” error each time I attempt to include an attachment. I’ve confirmed that the binary data is being correctly retrieved, and I’m using the correct variable name for the attachment. However, the error persists. Has anyone encountered a similar issue or have any insights on how to resolve th…

Issue With Downloading Outlook Attachments

Hi @adamjabarry, for this one no updates so far but will keep you posted if there are any updates!

[J_Oppus]

Thank you for your help. Is there any way to do this alternatively? What if I moved to self hosting N8N?

[mohamed3nan]

Self-hosting is more complicated when it comes to authentication.

Just wait for help—maybe someone knows how to fix this particular issue and can confirm if it’s still a known bug…

[J_Oppus]

Okay. Thank you for your help!
