I checked there isn’t already an issue for the bug I encountered.

Hello, this is my first post as a programmer, please don’t judge harshly, thank you.

Issue:

I’m using the 0x Next.js swap dApp example from the 0x documentation on the Polygon network in my application. Everything works correctly except for “MATIC”.

I can’t swap this token; it doesn’t recognize the balance and says there’s insufficient balance. What could be the problem?

I cant sell MATIC token, but can buy MATIC correct

In the console, I see errors like:
