Unable to send binary data with HTTP request node

Questions
1

Hi, I want to send a binary file with a post request, and I need to post it with a form-data multipart option. I am looking for something like we get in postman where we could pass the binary data in form with a key and data being the value of that key.

I am very sorry, but multi-part in combination with binary data is currently sadly not supported.

I want to send the binary file in this format: {“key”: file}, I tried doing this:
requestOptions.formData = {“random_key”:requestOptions.body}
But its giving me error while doing: npm run start
I> am getting following error:

It seems like it can not find the module n8n-core for some reason and does therefor not start.

So your best bet is to simply execute the lerna command again: lerna bootstrap --hoist
