Encountering No help topic for chain using lncli chain getblockheader command

[mohamedawnallah]

Description:
Apologies for the dump question, but I'm encountering an issue where I receive a No help topic for {command} message, even though the {command} in question is present in the Shell code sample provided in the Lightning Engineering documentation. For instance, when using a command like lncli chain getblockheader.

Referenced Documentation:
Lightning Engineering API Docs - Get Block Header

Additional Context:
I've compiled lnd from the source

You need to include the proper build tags. E.g. make install tags="chainrpc". Or just use the make release-install command that includes all build tags the release binary would contain.

Also see the "Tags" section in https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md#installing-lnd-from-source.

Thanks! I have already followed the tags section in the docs, but I've just found the issue. I created aliases for lnd-debug and lncli-debug to use shorter commands. However, lnd-debug and lncli-debug were not getting updated when executing make install tags="..." and it is supposed to since it's meant for release purposes. I resolved the issue by removing the aliases, and now it works 👍.
