trpc client request size limits?

I am sending a pretty sizable request and am seeing

[TRPCClientError: JSON Parse error: Unexpected token: <]

[TRPCClientError: JSON Parse error: Unexpected token: <]

I am not sure where the unexpected token is coming from or how to further debug this. My trpc client looks like

this.trpcClient = createTRPCProxyClient<TendrelAppRouter>({
      links: [
        loggerLink(
          enabled: _ => true
        }),
        httpBatchLink({
          url: stage.endpoint,
          headers: () => ({ bearer: this.workerAuthToken }),
        })
      ],
      transformer: superjson
    });
  }

this.trpcClient = createTRPCProxyClient<TendrelAppRouter>({
      links: [
        loggerLink(
          enabled: _ => true
        }),
        httpBatchLink({
          url: stage.endpoint,
          headers: () => ({ bearer: this.workerAuthToken }),
        })
      ],
      transformer: superjson
    });
  }

Get tRPC procedure latency?

Hi all, is there a supported mechanism to run common code to all procedures, say if I want to get latency metrics. I want to run the same latency math on all my procedures. I could create a helper function that I just have to remember to wrap all my procedure code in but just wondering if there's some supported tRPC way of doing this?

Nested keyof

Hi all, I am trying to use a fancy type to get a nested keyof effect. I found this code snippet online:

type NestedKeyOf<ObjectType extends object> = {
  [Key in keyof ObjectType & (string | number)]: ObjectType[Key] extends object
    ? `${Key}.${NestedKeyOf<ObjectType[Key]>}`
    : `${Key}`;
}[keyof ObjectType & (string | number)];

type NestedKeyOf<ObjectType extends object> = {
  [Key in keyof ObjectType & (string | number)]: ObjectType[Key] extends object
    ? `${Key}.${NestedKeyOf<ObjectType[Key]>}`
    : `${Key}`;
}[keyof ObjectType & (string | number)];

and when using it on the declaration side it definitely works, but I am having trouble using it to index into the type. here's a link to the code snippet: https://www.typescriptlang.org/play?#code/C4TwDgpgBAchDOwIBMDSEQHkBmAeTARgFYQDGwAKuNBAB5IB2y8UA9sWcAHxQC8UAbwBQUKAG10IKAEsGUANYZW2KIRLkqkKADIoACkQAnWQHMoAHygMArgFsCEQwEoAugC5VHDdQkYXUOkZmNi9gEVEoAH4oAAMAEgFJAF8AOgS4RBRJHHxQzQhfEBcuJJjw0Q94xIxSgG4hJLFFEGVPdUpqHX0jUwsrOwdnF3qhUC0AMVZWPkFyqAIAQ0MPYQi1+YWALw8ehhM5pIAaOewpneBjPYahIVJWBkQFDA8MpDQMHMnWHn4AIkXDClFptfiM7g9gFBTqwPF8ZqsIgCVsCPP8tr8jiczlBftDfg0oAsWODEGD7o9DAhrAAbSH8aFNPy1IA

trpc + AWS Lambda (through cdk)

Hi all, has anyone successfully integrated tRPC with AWS Lambda? My current stack is API Gateway + Lambda, all created through cdk. I am trying to figure out how to hook up the tRPC router and client to the lambda code. This is my first time using tRPC 😅
