For now i disabled it. Is there a better long term solution?

Thanks, could you raise a bug ticket along with a small reproduction? I have a good idea what’s causing this and falling back to your last working release should be fine

Thanks. I don't have a previously working release with it working, I've just set up trpc.
I'm not sure I will have time to make a repro in the next few days/weeks unfortunately. Will try when I can.

If you can share details about your tRPC setup on the server that would be perfect

Alex / KATT 🐱•4mo ago

No stress about exact reproduction, but if you've just setup trpc maybe you could give us the steps you followed roughly? We just released some new features that seem to create issues in your setup even though we thought our tests covered all edge cases I was able to reproduce this and rolled back the code caused it 11.0.0-rc.351 should be good

Thank you very much for the quick reaction !
