FlowModule Breaking: Prefix not valid syntax?

[crLawther]

When working through this, the replacer script replaces the value of the FlowModuleId with the syntax below (M: as the prefix and suffix) but there seems to be no mechanism to updated these flow automatically when they get deployed causing the flows to fail.

Can you confirm? I missing something?

      "Parameters": {
        "FlowModuleId": "${M:broadcast-message-module:M}"
      },

            "ErrorType": "NoMatchingError"
          }
        ]
      }
    }
