LGTM, I would also like to suggest whenever we catch a FailedToRetrieveComponentMetadata exception, to additionally suggest the user to make sure that they have set all the necessary environment variables and point them to the nice documentation you have added here.

For example, if the user has not set the RPC, instead of:

Error: Error connecting to the RPC

We could show something like:

Error: Error connecting to the RPC. Please make sure that you have set all the required environment variables correctly. You can read more about the configurations in this/doc/section.
