Failed IBodyProducer coercion produces opaque TypeError on text mode files #286
Description
It seems the API to upload files is broken. Below is the code that I am using to upload a file to Infura's IPFS gateway
from twisted.internet.task import react
import treq
_IPFS_API_GATEWAY = 'https://ipfs.infura.io:5001/api/v0'
_IPFS_ADD_FILE_ENDPOINT = f'{_IPFS_API_GATEWAY}/add'
def _upload_to_infura():
f = open('file.txt')
return treq.post(_IPFS_ADD_FILE_ENDPOINT, files={'file': f})
def main(reactor, *args):
d = _upload_to_infura()
d.addCallback(lambda response: print(response))
return d
react(main, [])
On running the code, this is what I see
Traceback (most recent call last):

The library chickens out even before sending data on the wire.
