#289 swamp config set crashes with YAML serialization error

Opened by stack72 · 5/7/2026· Shipped 5/7/2026

Running swamp config set update.auto enabled crashes with:

FTL error: TypeError: Cannot stringify undefined
    at DumperState.stringifyNode (https://jsr.io/@std/yaml/1.1.0/_dumper_state.ts:822:11)
    at DumperState.stringifyBlockMapping (https://jsr.io/@std/yaml/1.1.0/_dumper_state.ts:698:32)
    ...
    at async Command.<anonymous> (.../src/cli/commands/config.ts:117:9)

The UpdatePreferencesFileRepository.write method fails when serializing the updated config to YAML. swamp config get and swamp config list work fine.

Steps to reproduce:

  1. swamp config set update.auto enabled

Expected: Config value is set successfully. Actual: Fatal error with YAML stringify failure.
