All values must be numeric

Error message

All values must be numeric

What it means

On the versioned language-pack script route (superset/views/core.py:724), the <version> path segment must match ^[0-9a-f]{12}$ — a 12-character lowercase hex content hash (it keys immutable browser caching of script.js). Anything else (short hash, 'latest', uppercase, non-hex) aborts 400 'Invalid language pack version'. The lang check runs before this, so a bad lang yields error 505 instead.

Solutions

1. Obtain the version from get_language_pack_version(lang) (the same helper the server uses) and request exactly that
2. Re-fetch the current version whenever translations change instead of caching it indefinitely
3. Normalize: lowercase hex, exactly 12 characters

Example fix

# before
url = f"/language_pack/{lang}/latest/script.js"  # 400

# after
from superset.utils.language_pack import get_language_pack_version
version = get_language_pack_version(lang)
url = f"/language_pack/{lang}/{version}/script.js"

import re

def valid_version(v: str) -> bool:
    return bool(re.fullmatch(r"[0-9a-f]{12}", v))

const isPackVersion = (v: string): boolean => /^[0-9a-f]{12}$/.test(v);

When it happens

Trigger: GET /language_pack/pt_BR/v2/script.js, /language_pack/en/ABC123DEF456/script.js (uppercase), a 40-char git-style sha, or an empty version segment; also hardcoding a version string in templates instead of reading the current pack version.

Common situations: Custom HTML templates or reverse-proxy rewrites that pin a version literal; after a Superset upgrade the pack content hash changed and old clients request a version they computed differently; tooling passing the translations file mtime or build number as version.
