TS 2.0.4 Migration Failed - WASM Bad Magic Number #4621
Description
I received the following error message when attempting to step up from 2.0.3 to 2.0.4. I have tested and I can switch back to 2.0.3 and I can keep things progressing on my prototype. If I am going to use this in production, I want to learn to debug these types of errors better. Are there any recommendations on how I can further investigate this and hopefully find what in my setup is causing the issue?
ARM Windows Host running spacetimedb on WSL Ubuntu 24. Using typescript for both backend and frontend.
These are my upgrade steps.
- spacetime version upgrade
- pnpm update spacetimedb && pnpm install
- (cd spacetimedb && pnpm update spacetimedb && pnpm install)
