Incorrect summary output

[lukemovement]

System information

• OS: Linux Ubuntu 22.04
• TensorFlow.js npm: 4.9.0
• Environment: Node v18.16.0, ts-node-esm v10.9.1

Describe the current behavior
The error message seems to state that the summary of the model is incorrectly printed. This error message does not appear within the code pen link provided, however, it does not finish the training on code pen either.

Describe the expected behavior
Not the error message below
