Expected one of [b'HEAD', b'object', b'POST'] when sending pre-flight OPTIONS request #391

The following error occurs when you request http://localhost:6800/schedule.json with Axios:

Error Message

Expected one of [b'HEAD, b'object, b'POST']

The cause is an error caused by pre-flight (OPTIONS) prior to POST request.

How should I handle this?

Digenis commented 3 years ago

If it's not returning 405, it's a scrapyd or twisted bug.

If it's returning 405, its an axios bug.

In any case, if this method is useful, feel free to open a pull request and add it to the webservice

FYI, there are some links here in an axios issue to avoid sending the OPTIONS request (or to have it swallowed by a proxy): https://github.com/axios/axios/issues/888
