Function preprocessIntFieldAsString

pkg/workflow/config_preprocessing.go:54–87

preprocessIntFieldAsString converts the value of an integer config field to a string before YAML unmarshaling. This lets struct fields typed as *string accept both literal integer values and GitHub Actions expression strings (e.g. "${{ inputs.max-issues }}"). If the value is an int, int64, float64,

(configData map[string]any, fieldName string, debugLog *logger.Logger)

// with "${{" and ends with "}}"); any other free-form string is rejected
// and an error is returned.
func preprocessIntFieldAsString(configData map[string]any, fieldName string, debugLog *logger.Logger) error {
	if configData == nil {
		return nil
	}
	if val, exists := configData[fieldName]; exists {
		switch v := val.(type) {
		case int:
			configData[fieldName] = strconv.Itoa(v)
			if debugLog != nil {
				debugLog.Printf("Converted %s int to string before unmarshaling", fieldName)
			}
		case int64:
			configData[fieldName] = strconv.FormatInt(v, 10)
			if debugLog != nil {
				debugLog.Printf("Converted %s int64 to string before unmarshaling", fieldName)
			}

				debugLog.Printf("Converted %s uint64 to string before unmarshaling", fieldName)
			}

			if !isExpression(v) {
