Here is my server:

import { initTRPC } from "@trpc/server";
import type { CreateAWSLambdaContextOptions } from "@trpc/server/adapters/aws-lambda";
import { awsLambdaRequestHandler } from "@trpc/server/adapters/aws-lambda";
import type { APIGatewayProxyEvent } from "aws-lambda";

function createContext({
event,
}: CreateAWSLambdaContextOptions<APIGatewayProxyEvent>) {

return {
event: event,
apiVersion: (event as { version?: string }).version ?? "1.0",
user: event.headers["x-user"],
};
}
type Context = Awaited<ReturnType<typeof createContext>>;

const t = initTRPC.context<Context>().create();

const router = t.router;

const appRouter = router(...);

export type AppRouter = typeof appRouter;

export const handler = awsLambdaRequestHandler({
router: appRouter,
createContext,

});

import { initTRPC } from "@trpc/server";
import type { CreateAWSLambdaContextOptions } from "@trpc/server/adapters/aws-lambda";
import { awsLambdaRequestHandler } from "@trpc/server/adapters/aws-lambda";
import type { APIGatewayProxyEvent } from "aws-lambda";

function createContext({
event,
}: CreateAWSLambdaContextOptions<APIGatewayProxyEvent>) {

return {
event: event,
apiVersion: (event as { version?: string }).version ?? "1.0",
user: event.headers["x-user"],
};
}
type Context = Awaited<ReturnType<typeof createContext>>;

const t = initTRPC.context<Context>().create();

const router = t.router;

const appRouter = router(...);

export type AppRouter = typeof appRouter;

export const handler = awsLambdaRequestHandler({
router: appRouter,
createContext,

});
looking online it seems like this might be an issue with typescript and node/browser types? i'm on the latest TS
