using import { useSubscription } from "@trpc/tanstack-react-query"; the word enabled does not occur anywhere in my code, the subscription looks like 
  sseSetupEvents: baseProcedure
    .input(z.object({ appId: z.string() }))
    .subscription(async function* ({ input, signal }) {
  sseSetupEvents: baseProcedure
    .input(z.object({ appId: z.string() }))
    .subscription(async function* ({ input, signal }) {

client side I see Error: opts is not an Object. (evaluating ''enabled' in opts') which is virtually the same error node_modules/.pnpm/@trpc+tanstack-react-query@11.0.1_@tanstack+react-query@5.71.0_react@19.1.0__@trpc+clie_acde9ae0fea49fdc035d62a8c18c34ef/node_modules/@trpc/tanstack-react-query/dist/internals/subscriptionOptions.mjs (10:34) is reported in the stack, which does contain 
/**
 * @internal
 */ const trpcSubscriptionOptions = (args)=>{
    const { subscribe, path, queryKey, opts } = args;
    const input = queryKey[1]?.input;
    const enabled = 'enabled' in opts ? !!opts.enabled : input !== skipToken;
/**

    const { subscribe, path, queryKey, opts } = args;
    const input = queryKey[1]?.input;
    const enabled = 'enabled' in opts ? !!opts.enabled : input !== skipToken;
now the million dollar question is why is that method called without opts it's a bug in trpc opened PR
