move_chunk_source_error_changelog.js asserts that exactly one moveChunk.error changelog entry exists after a failed migration. Under continuous config server stepdowns, mongos internally retries the _configsvrMoveRange command when the config primary steps down mid-migration, causing the donor shard to run the migration twice and produce two changelog entries.

The test should be excluded from this suite, similar to the existing exclusion of refine_collection_shard_key_changelog.js.
