morgan returns server-side middleware which is supposed to be used for logging incoming requests. You're trying to use it client-side to log outgoing requests, which isn't its purpose. For what you're trying to accomplish axios-debug-log should work, but in order for it to log requests in the combined format, you'll have to configure it yourself.

For reference, this is how morgan currently defines the combined log format:

morgan.format('combined', ':remote-addr - :remote-user [:date[clf]] ":method :url HTTP/:http-version" :status :res[content-length] ":referrer" ":user-agent"')
