Begin with the linked Sentry report and the stack trace at node_modules/@walletconnect/sign-client/dist/index.cjs.js. Trace the repository code that emits the chainChanged event and investigate why the reported data value of 1 is rejected. Done means the invalid-event error is resolved and the affected flow is verified.
