Amazon States Language Errors - amazon-web-services

Question

I am creating an AWS State machine - I am getting an error:
Here is the site that the error links too: https://docs.aws.amazon.com/step-functions/latest/dg/concepts-amazon-states-language.html
I have been combing through my state machine code for hours, and I can't figure out what is wrong with it. Previously when I had errors, they showed up in the GUI - but for this, it just says there is an error with no indication of where the error is from.
Here is my state machine visualized:
Here is the code for my state machine:

},
"Wait 2":{

"Next":"Transform 3"
},
"Wait 3":{
"Type":"Wait",
"Seconds":1,
"Next":"Transform 4"

}
}
A pointer in the right direction would be extremely helpful.

Answer 1

I figured it out.
"CatchAllFallback":{
"Type":"Pass",
"Result":"This is a fallback from any error code",
"End":false
},
Was defined multiple times - which was causing the error.
