How do I convert Json files into binary data for the OpenAI Transcribe node

Questions
1

The questions asked didn’t solve my problem, so I’m asking my own.
I want to use the Telegram Get Node to convert an image file into a binary file so that it can be processed by the OpenAI Transcriber. However, I can’t find the right way to do it. I came across the Convert to File Node, but now I’m stuck.

Describe the problem/error/question

###Cannot read properties of undefined (reading ‘split’)
###i want convert the Json data what i get by the previous node in to binary data, that the OpenAi transcriber node can analyze that.

What is the error message (if any)?

###Cannot read properties of undefined (reading ‘split’)

  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Here you go.

Is it also possible to leave out the Telegram get the file node and bind the code node directly to the Telegram trigger node? i mean i saw that in one video.

Yes, can be done. You can use HTTP Request node to get the file.

Hey, saw your suggestion about use of MIME node. How does tis node function and what it is good for? How do you use it, I mean in which situations?

Hi, it’s a code node, that helps to transform file MIME type.
Basically, we are setting the file type manually.
