Error message

encountered HTTP status {0} when reading the existing meta file

What it means

WriteDefaultMetaError::Http — while checking for an existing meta file over the HTTP asset source, the server returned the non-success status in the payload (e.g. something other than 404 when probing). Verify the HTTP asset source's availability and the path.

Solutions

  1. Check that the remote asset source/URL serves the meta file correctly
  2. Treat 404 as no existing meta and proceed with default generation
  3. Fix the HTTP-serving backend returning the error status
