XF 2.1 Resources API

Hi am running into the internal error below, even though I am specifying the username parameter: https://screencast-o-matic.com/screenshots/u/hh9M/1575889079384-12707.png . User is a superuser, posting to /api/resources/ to create a new resource. Other API calls set up and working; e.g. get resource by ID, same credentials being used. Any ideas on what else to try/set much appreciated.

@Lukas W. thanks for the pointer but sadly still no joy. Have added/tried all the combinations I can think of - user_id on it's own, username on it's own, and both as below but still the same error and the same error log. Can you see what I'm missing/getting wrong here?

Request state
array(4) {
["url"] => string(189) "/api/resources/?api_bypass_permissions=1&resource_category_id=4&title=Test%2016th%20Dec%202019&tag_line=What%20a%20test&description=This%20is%20a%20test%20description&resource_type=fileless"
["referrer"] => bool(false)
["_GET"] => array(6) {
["api_bypass_permissions"] => string(1) "1"
["resource_category_id"] => string(1) "4"
["title"] => string(18) "Test 16th Dec 2019"
["tag_line"] => string(11) "What a test"
["description"] => string(26) "This is a test description"
["resource_type"] => string(8) "fileless"
}
["_POST"] => array(0) {
}
}
 
Cracked it: needed to add "xf_api_user" (id) to the header, as "api_bypass_permissions" = 1 in the params was not bypassing the auth.
 
It is bypassing the auth, but it still needs a user to create the resource with, which is taken from the header.
 
For future readers:
API key should be super user, and header should contain XF-Api-User (id) key. It's the way of setting \XF::visitor() value for third party access (without login).
