BigInt in Session causes Do not know how to serialize a BigInt

[siddharthsharma94]

What is the problem?

createSessionToken uses JSON.stringify on the publicData being passed in, which doesn’t support BigInt. Seems like a use case for superjson instead?

What are detailed steps to reproduce this?

1. Use BigInt in Schema
2. Create a session variable with BigInt

Run blitz -v and paste the output here:

Prisma supports BigInt since a while now. Can we use SuperJson to serialize the publicData? It looks like the merge request went stale and the stuff was moved to blitz-auth now.
