Does anybody now how to fix cors policy error?

I am facing this error: Access to fetch at 'http://localhost:3002/trpc/getBotTag?batch=1&input=%7B%7D' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. But this is only happening on "use client" components....

Call multiple TRPC endpoints from onSuccess()?

I would like to create an API chain for analysing a geographic area where one successful API call can lead to multiple new API's being called to render the components in the right orders for the user. This works really well for single API calls, but when combining multiple of them together to be triggered at a onSuccess() call, the trpc combines them all together instead of taking them one by one. Does anyone know how to solve this?...

How to set sizeLimit > 1MB (to solve 413 error)?

Hi all, I am trying out the T3 stack where I want to send area polygons given by the user to my NextJs backend using TRPC. It worked well for smaller polygons drawn by hand, but one I allowed my users to upload files over 1MB I run into the problem of '413 (Body exceeded 1mb limit)' I found in the NextJs documentation:...

How to manage server to server communication

Would managing headers this way work in nextjs as server to server communication? or does next manage multiple requests in parallel so there is the possibility it will send the token from one user to another user? Do I have another way of using TRPC from the server side of next if the TRPC server is hosted in other place?...

Can someone explain to me the use of tRPC in server components?

I can really see the need for tRPC in client components but can someone explain to me how you would go about it in server components? In server components I can directly retrieve data from my database with Drizzle or Prisma. If I'll use tRPC in the server component will it just make a request to the server where it already is at that moment through the API or is tRPC able to handle this and run the code without making an extra call?...

Type errors in lambda integration

I really don't know where to start with this error.... I'm going to be integrating tRPC into a lambda, and I have a merged child router, but I'm getting this type error: ``` Type 'CreateRouterInner<RootConfig<{ ctx: object; meta: object; errorShape: DefaultErrorShape; transformer: DefaultDataTransformer; }>, { users: CreateRouterInner<...>; }>' is not assignable to type 'AnyRouter'. The types returned by 'createCaller(...)' are incompatible between these types....

Hybrid application with offline and online mode setup with tRPC

Hi, I was wondering if I could setup tRPC in way that one http link is using local API (for offline mode) and another uses online http link for when user logs in and connects to online service. What would be best setup, is it fine if I use splitLink in this case. Is tRPC ment for this kind of setup. Thanx...

Next cookies() not being set on Mutation in App Dir (T3 Turbo)

Trying to set cookies inside TRPC using Nextjs App Router, using the T3 Turbo setup. Setting cookies works fine inside Queries, but cookies are not set inside Mutations. Maybe I'm doing something wrong, not very up to date with TRPC + App Dir, or it could be a bug in next, not sure. ```ts...

How to serve files with trpc?

Is is possible to serve files with trpc? E.g., by creating a middleware and returning directly from the middleware? I can't seem to serve files with trpc. Should a separate server be set up just for file serving?

tRPC in Next without api rotes

Hello! I have NextJS app that gets data in gSP using some third-party client. This data comes untyped, and i'm thinking if tRPC can help me to manage this behavior in a better way, than just zod validation. One more thing - i do not want to make some public endpoint for quering this data. But I can't find any examples of tRPC usage in NextJS without API routes. Does it mean that tRPC do not fit my task as it actually "a gates of BE part"?...
