Solutions

1. Call it with no arguments: `ghidra trace info`

Example fix

// before
ghidra trace info all
// after
ghidra trace info

import shlex
def no_args(command: str) -> bool:
    return len(shlex.split(command)) == 0

try:
    ghidra_trace_info(debugger, command, result, internal_dict)
except RuntimeError as e:
    if str(e).startswith('Usage: ghidra trace info'):
        # drop arguments and retry
        ...
    raise

When it happens

Trigger: `ghidra trace info verbose`; `ghidra trace info all`.
