Title
Add validation to exclude invalid
user_id
(e.g. email or phone number) from Anthropic metadataRelevant issues
Fixes #10106
Type
🐛 Bug Fix
Changes
This PR introduces a validation check for the
user_id
field in the_litellm_metadata
dictionary to ensure it does not contain personally identifiable information (PII) such as emails or phone numbers.Rationale
Anthropic requires that the
user_id
in metadata must be a UUID, hash value, or other opaque, non-identifying identifier. It must not contain any personally identifiable information such as names, email addresses, or phone numbers. Including such data can lead to the API rejecting the request with a400 Bad Request error
. ViewThis update ensures that if an invalid user_id is provided (e.g. an email), it will simply be excluded from the metadata, preventing avoidable request failures.
