#20821 pants help-all errors on missing help text, but help text is not a required field. Issue created by TansyArron Describe the bug A clear and concise description of the bug. When running

pants help-all

on my own repo I get:

$ pants help-all
11:11:51.53 [INFO] Initializing scheduler...
11:11:55.85 [INFO] Scheduler initialized.
11:11:56.19 [ERROR] type object 'MyCustomField' has no attribute 'help'

See <https://www.pantsbuild.org/v2.19/docs/troubleshooting> for common issues.
Consider reaching out for help: <https://www.pantsbuild.org/v2.19/docs/getting-help>

I would have expected either: • help is a required parameter and

pants help-all

fails with the above message. • help is not a required parameter, and

pants help-all

does not error. Pants version Which version of Pants are you using? 2.19.1 OS Are you encountering the bug on MacOS, Linux, or both? Linux Additional info Add any other information about the problem here, such as attachments or links to gists, if relevant. Super minor issue, and I've fixed it by adding help text, but it seemed like the sort of inconsistency we should fix. pantsbuild/pants
