ERROR 1105 (HY000): unknown error: unable to cast nil to bool #902

Error executing example query:

SELECT repository_id,
       file_path,
       uast_extract(uast(blob_content, LANGUAGE(file_path), '//uast:Import/Path'), "Value") AS imports
FROM commit_files
NATURAL JOIN refs
NATURAL JOIN blobs
WHERE ref_name = 'HEAD'
  AND LANGUAGE(file_path) = 'Go'
  AND ARRAY_LENGTH(imports) > 0;

ajnavarro commented 5 years ago

The problem appears to be when LANGUAGE is used without blob_content second param.
