Describe the problem/error/question

I’m having an issue with the HTTP Request to download a PDF. When I make the call, it seems to download everything fine, but when I try to preview the document by using the download button it downloads a file, but the file seems to be corrupted and I’m unable to view. If I try to preview directly in editor, I get an empty gray file. I’m able to make the call and download just fine with cURL. Everything seems ok about mime type returned by the URL.
And all is working fine for png / jpg.

Welcome to the community @djiworks :tada:

By default, n8n uses memory to store binary data which can cause crashes like one you’re experiencing when handling large binary data files. To avoid this, set the environment variable N8N_DEFAULT_BINARY_DATA_MODE to filesystem which will allow you to save data to disk instead of in memory.
You can find more info in our docs here: Binary data > Enable filesystem mode
