Error message

wrong taskType supported task types are: %v (joined validation errors: %s)

What it means

Class-settings validation for the text2vec-google module failed on one or more checks: a base-settings validation error, a missing projectID when a non-default API endpoint is set, or a taskType outside the supported list. This is the joined message of all accumulated validation errors (the %s), so the specific offending field is in the joined details, not this prefix.

Solutions

1. Read the joined validation details in the full message to see which checks failed
2. Set XGoogleClientProjectID when using a custom ApiEndpoint
3. Set taskType to one of the supported values (e.g. RETRIEVAL_DOCUMENT, RETRIEVAL_QUERY) or leave it unset for auto-selection
4. Fix any base class-settings errors reported alongside
