ParseError code=-1 error=Invalid struct: No value associated with key CodingKeys(stringValue: "objectId", intValue: nil) ("objectId")

I tried your code and unfortunately couldn’t replicate the error.

The only changes I made were supplying default texts to your String? properties.

Just to make it clear, You’re saying “Saved Message” doesn’t print and instead the ParseError ?

do you have any extension to the Message struct maybe somewhere you forgot about? maybe a thirdparty library you loaded?
