error extracting batch details from name %q: %v

Error message

error extracting batch details from name %q: %v

What it means

ExtractBatchDetails could not regex-match the batch name returned in the operation metadata against the expected projects/<project>/locations/<location>/batches/<batch_id> shape, so the created batch cannot be decomposed into project, location and batch ID.
