Unable to parse creator ID from URL: {url}

Error message

Unable to parse creator ID from URL: {url}

What it means

ValueError from parse_creator_info_from_url (media_platform/bilibili/help.py) when the input is neither an all-digit string (pure UID) nor a URL matching space.bilibili.com/(\d+). Bilibili space IDs are numeric, so any non-digit slug, username-style URL, or malformed share link falls through to this raise.

Solutions

1. Pass the numeric UID directly ('434377496') or the full space URL 'https://space.bilibili.com/434377496'.
2. Pre-validate with a digit check or the space.bilibili.com regex before calling.
3. Trim/normalize user input (strip whitespace) before parsing.

Example fix

# before
parse_creator_info_from_url(' 434377496\n')

# after
parse_creator_info_from_url('434377496')

When it happens

Trigger: Passing a space URL with a non-numeric path (rare vanity/legacy forms); an empty or whitespace-only string failing url.isdigit(); a URL like 'https://space.bilibili.com/' with no ID; query-only strings where the digits sit in a param instead of the path.

Common situations: Copy-pasting creator links that got truncated at the digits; feeding a username or display name instead of the numeric UID; leading/trailing spaces or a '\n' smuggled in from CSV input.

Understand the failure class

• Parsing and encoding errors: unexpected token, malformed input — why parsers reject input and how to find the real culprit.
