Cannot download binary file to local

[Binh_Vo]

im new to n8n, may i ask why i cannot download the binary file audio to my local desktop?

im sure the file path is existing and available to write (i downloaded images before in this folder)

current version is 1.107.3, Windows 11, self-host

thank you for helping

Hello @Binh_Vo ,

It’s great that you’re diving into n8n – I totally understand that the start can be a bit tricky, but you’re doing awesome by asking questions.

Regarding your issue with downloading the binary audio file to your local desktop: It seems like the problem might be with the previous node not outputting the audio file in the correct format that the Read/Write Files from Disk node expects. This node requires the input to be in binary format so it can handle it properly and write it to your local storage.

Here’s what you can do :-

1.Check the Previous Node : Make sure that the node before the Read/Write Files from Disk is outputting the file as binary data (e.g., audio data in the “data” field). If it’s not, the write node won’t know what to do with it.
2.File Path & Permissions : Also, double-check that the file path you’re using for saving the file is correct and that the folder has the right permissions to allow n8n to save to it.

Good luck, and don’t hesitate to ask more questions – we’re all learning and growing together!

thanks for answering my question. i’ve solved this problem:

we have to set the response format of this “generate audio” OpenAI node in order to download it. otherwise, the download node will error although we got binary data from the previous node.
