language must be a non-empty string

Error message

language must be a non-empty string

What it means

Optional-field type guard in parse_search_args: "language" was provided but is not a string, or is empty/whitespace after trimming. The parser expects a language code such as "en" or "en-US"; any other shape fails here. The faulting input is a non-string or empty language value.

Solutions

1. Pass language as a non-empty BCP-47-style code string, e.g. "en" or "de".
2. Omit the field entirely to use the SearXNG instance's default language.
3. Validate/normalize the language value before invoking the tool.
