trpc client request size limits?

the request never makes it to the server, so somewhere the trpc client is trying to parse the request for some reason and i think having it too big makes it introduce a funky token?

Get tRPC procedure latency?

a middleware will only run before a procedure right?

ohh no it wasnt. I didn't do the initial setup of this codebase, didn't even notice strict wasnt on. Enabling strict mode and removing the extra <Context> works, compile-wise -- not sure yet about runtime

ok I got it working -- truly dont understand this yet but adding Context to the type parameter of create did the trick:

export const createContext = ({event, context}: CreateAWSLambdaContextOptions<APIGatewayProxyEventV2>) => ({});
type Context = inferAsyncReturnType<typeof createContext>;

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

export const createContext = ({event, context}: CreateAWSLambdaContextOptions<APIGatewayProxyEventV2>) => ({});
type Context = inferAsyncReturnType<typeof createContext>;

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

it definitely could be an apig oddity, though I can see it in the console returning the json response correctly. Maybe I need to find somewhere in between that I can inspect to see where that response is getting lost... Like a debug log from the trpc client or something

it's just the return value isn't getting processed correctly

yep. and I tested out calling the api directly in my aws console, confirmed its working. Also confirmed that the lambda is getting invoked when I call it from the client by double checking logs

I was able to pass in superjson and get around the error, but then the response from my lambda was coming back undefined -- I was wondering if the default transformer would've just handled the response correctly
