Entered unreachable code using an illegal connection string

[MagnusOestlund]

Bug description

Hi!

I am submitting this since the package asked yes/no if I wanted to report the bug, and since the error message was the unreachable code was reached I figured this may be interesting for you to know.

This submission is just to help you, and thanks for prisma, it's really great! I believe the problem is in my connection string so from my part this doesn't need any fixing if you don't want to fix it due to it giving that error.

I used this in my .env file:

DATABASE_URL="sqlserver://81.95.105.76:1433;database=DBNAME;user={SERVER/USERNAME};password={PWD;};encrypt=true;TrustServerCertificate=true"

And on running prisma db pull:

:\Users\username\source\vscode\prisma db pull

Prisma schema loaded from prisma\schema.prisma
Environment variables loaded from .env
Datasource "db": SQL Server database

✖ Introspecting based on datasource defined in prisma\schema.prisma

Oops, an unexpected error occurred!
Error in Schema engine.
Reason: [libs\user-facing-errors\src\quaint.rs:125:18] internal error: entered unreachable code

How to reproduce

Set the .env file to match my DATABASE_URL setup, then try and connect with a normal empty connection to pull the existing database with prisma db pull.

Expected behavior

I would have expected an error message that my connection string was incorrect. If you compare how the documentation example is, then this matches the string I tried, but since it doesn't connect I can be sure the problem lies in my code.
