Logging and debugging
To help debug issues with commands, the Twilio CLI also supports logging via the -l flag.
You can decide what level of logging you'd like by using the -l option. The valid levels of logging messages are debug, info, warn, error, and none.
All debug, informational, warning, and error logs are sent to stderr. This is so it can be easily separated from the command output.
For example, suppose you're unable to list your messages and aren't sure why:
$ twilio api:core:messages:list
» twilio-cli encountered an unexpected error. To report this issue, execute the command with the "-l debug" flag, then copy the output to a new issue here: "https://github.com/twilio/twilio-cli/issues"
In this case (and most cases), debug logs will help you inspect the issue and see errors in greater detail:
$ twilio api:core:messages:list -l debug

Instead of an opaque error message, you now have logs that indicate the issue is due to an invalid URL in the request. Time to verify that you have the correct Edge and Region set for your account!
