Error message

asset meta file already exists, so avoiding overwrite

What it means

WriteDefaultMetaError::MetaAlreadyExists — the server declined to write a default meta file because one already exists at the target path; the existing meta is preserved. This is a benign guard against overwriting user-tuned meta; delete the file if regeneration is wanted.
