Occasionally, in Bitbucket Pipelines, the displayed logs aren't showing under the correct command. The logs are correctly uploaded. However, they aren't mapped to the correct command. Also, the log doesn't download completely when downloaded from the UI.

Alternatively, the full logs can be obtained via API. The "Range" can be adjusted accordingly if the logs are large.
