# X_ERROR_FIX_INVALID

## Means

an error's fix line is not a runnable instruction

## Typical cause

the `errors` step read a `fix:` that is empty, or one that advises (`check`, `make sure`, `try`, `see the docs`) with no command, call or file path in it

## Fix

the `fix` names the offending `<file>:<line>` — rewrite that `fix:` as a runnable command, a call, or an edit naming a file
