Remote Functions: `query` was prerendered during the build process

[mustofa-id]

Describe the bug

While trying out Remote Functions, I noticed that using the query function causes the build to fail. This doesn’t happen with the load function, the build completes fine.

It seems like query is being prerendered during build. I'm not sure if this is expected or if I'm missing something in the setup.

Reproduction

See: Stackblitz

echo "DB_URL=localhost" >> .env

npm run build # OK

# uncomment code lines in todo.remote.js then

npm run build # again, it will fail.
