ConfigureSync and Watch Contract Events CONFIRM BUTTON It doesn't work

[Cainuriel]

I am following the tutorial for configuring events for contracts

Moralis Syncing and Indexing Smart Contract Events

I think I have correctly filled in all the fields but the confirmation button does not work.

I attach images of the form in case you see any errors.

I could not upload two images and I upload in this reply the part that I am missing.
