This is returning `blob_metadata` which is defined as `blob.metadata` in [L1023 ](https://github.com/apache/airflow/pull/38398/files/d9bee99ce49d28a218fa9b97eba62f05e3332143#diff-82854006b5553665046db26d43a9dfa90bec78d4ba93e2d2ca7ff5bf632fa624R1023) and is an optional dict object. The test case for an empty blob is written, I have added it [here, in the other file on L582]( https://github.com/apache/airflow/pull/38398/files/d9bee99ce49d28a218fa9b97eba62f05e3332143#diff-76fef248bc8b2046dae5e6e1fe60dcb916e4114d85190c563454d2d123937b43R582-R593) -- This is an automated message from the Apache Git Service.
