compatibilityDate property
CompatibilityDate pins which Workers runtime behaviour the script runs under, as a plain calendar date ("2024-01-01"). Absent leaves the account's own default in force.
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? compatibilityDate;
