commitSha property
CommitSha is the tip the run pushed, clamped to 128 characters. Empty when it pushed nothing, which is the same case Changed reports false for.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? commitSha;
