/place template causes error during validation

[2mal3]

Validating a datapack (e.g. pack.zip) with a place template command (e.g. place template minecraft:fossil/spine_1 ~ ~ ~) leads to the following error:

Error: Plugin "mecha.cli.validate" raised an exception.

Traceback (most recent call last):

I have noticed that this does not happen if you leave out the ~ at the end (only place template minecraft:fossil/spine_1).

Ooh good catch! Looks like we're missing an argument parser. I should be able to fix this later.

@2mal3 Just fixed it in 718c907. This is released in v0.54.8. If you're using the check-commands action you can bump mecha with the version input.
