There are five more Sentry issues in
dx-clithat look like the same Windows compatibility cluster. Worth consolidating into this one rather than tracking separately:OSError: [Errno 22] Invalid argumentondg mcpOSError: [Errno 22] Invalid argument(variant)OSError: [Errno 22] Invalid argument(variant)OSError: [Errno 22] Invalid argument(variant)UnicodeEncodeError: 'charmap' codec can't encode characters in position 2-17MarkupError: closing tagwith garbled charactersCommon signal across all of them:
cli.os = windowsdeepctl@0.2.24__main__.py:<module>in the in-app frame — fails during entry-point initializationThe pattern is consistent with Windows cp1252 encoding choking on non-ASCII output:
Errno 22 Invalid argumenton Windows often means a path or filename contains a characterCreateFileWrejects (NUL,<,>,:,",|,?,*, or control chars) — OR a file descriptor flag combination Windows doesn't allow.'charmap' codec can't encodeis the canonical Python-on-Windows error when stdout's default encoding (cp1252) hits a non-Latin1 character.MarkupErrorwith garbled bytes is what Rich produces when its terminal output gets corrupted mid-tag — likely the same encoding cascade.If this issue takes a fix, suggest closing the other five Sentry groups as merged. If we want them as separate tracking entries first, the Sentry "merge" action under each one would fold them into DX-CLI-6.
Worth noting
dg mcpis in the culprit for DX-CLI-6 specifically — that subcommand is where the failure mode lands most often.github-actions commentedon Oct 12, 2026
