I investigated the failing typecheck.

Running npm --prefix apps/backend run typecheck on the current main branch produces the same Cannot find module '@devcard/shared' errors in multiple files (cards.ts, follow.ts, team.ts, profileService.ts, and validators.ts).

The changes in this PR are limited to removing any usages from cards.ts and handling error types safely. The remaining typecheck failures appear to be present in the base branch as well.

Hi @Harxhit,

This PR addresses the same type-safety improvements in cards.ts, but issue #547 was already assigned, completed, and closed via #579 before I opened this PR.

Could you please let me know if you'd like me to link this PR to a different open issue, or should I simply mark it as related to #547?

Thanks!

@keerthana266 Typecheck is failing could you please look into it.

Hi @Harxhit,

I merged the latest upstream/main into this branch, resolved the conflicts, regenerated the Prisma client, and verified locally that backend typecheck passes.

The backend-ci check is now passing successfully. The only remaining blocker appears to be the Vercel authorization/review requirement.

Could you please take a look when you have time?

Thanks!
