The error from the older version is a lot more indicative of what the actual problem is.

Start by reproducing the git-node v8 backport command with the nonexistent commit shown in the report, comparing the output from node-core-utils@3.4.0 and @node-core/utils@5.0.1. Trace the backport entry point and its error handling; done means the missing commit produces a specific, helpful error instead of Cannot read properties of undefined (reading 'replace').
