I created another command like usual, but it shows the “ValidationError: Expected a string primitive” error and I’m not sure why.
This is the at file:///home/egganto/Documents/Athena/src/commands/perimeter.js:157:33 it’s referring to:

export default perimeterCommand.toJSON();

This is the full error:

I tried checking if I missed any description/require attributes, and if I haven’t missed anything, I think it might not be missing something
