Describe the problem/error/question
When creating Mattermost credentials in self hosted n8n docker instance, I have a 400 HTTP error Bad request. In debug level log it does not show the HTTP request that fails. I have tried via curl and the Mattermost API v4 (Server 9.5.3) succeeds. The mattermost instance is another self-hosted one, different domain. Is there a way to have the HTTP request sended by n8n ? Axios have interceptors to log HTTP requests / response in debug level.
What is the error message (if any)?
