Please help me to understand this monorepo setup(specially deployment/build part)

[BlackBeardo]

ok so t3-turbo is exactly what i wanted since i am single dev for my own idea and i want to make it work on web as well as on mobile.
I have been working with next js(page router), mui, redux and all other libs since last 2 years and understand coding part pretty well.

with app router next js looks solid and I also want to try it in my current project so i choose t3-turbo. i am not good with monorepo. i have try pnpm monorepo for simple project once but that's it. turbo and this setup is little bit new to me but after work on it I understand it's benifits.

what I am trying to do is I use t3-turbo setup as it is and added one more workspace for my admin panel, which is basically copy of apps/nextjs. only change is name in package.json.

i created one page for my /contest where i will create forms and other ui part of CRUD for contest.

when i do pnpm dev:admin, it works fine. no errors on client or server. data fetching good, create delete api works.
problem shows up when i did pnpm build:admin, and then db, api and validators build passed but it faild with error pasted below:

 **I am not sure if I am doing right and something is missing in code or env or other configs i need to check for local build, or i have to keep server running before start build of some other things?

i am fairly new with this RSC and app router, can anyone help me to understand the flow with this kind/specifically this repo setup. i tried to deploy same code(whole monorepo) in vercel with my free account. and it having same issue.

anything is helpful for me since i am learning.**
