Prisma plugin does not work with ` previewFeatures = ["multiSchema", "views", "relationJoins", "queryCompiler", "driverAdapters"]` in prisma 6.8.2

When starting the server Prisma plugin does not work with previewFeatures = ["multiSchema", "views", "relationJoins", "queryCompiler", "driverAdapters"] in prisma 6.8.2

I think this is related to queryCompiler. When this is enabled I think the DMF that gets generated is more limited. Last time I tested this, in 6.7 queryCompiler was VERY broken to a point where it was completely unusable.

I would be very careful using this feature because it was dropping where which leads to returning data you tried to filter out which is really bad

i just checked with prisma 6.11 and it still has the issue with pothos.

with prisma 7, queryCompiler will probably be the default, so it is probably worth investigating what is missing either on prisma's side or on pothos side regarding the DMF

[macrozone]

@hayes as a workaround, i tried to use this approach here https://pothos-graphql.dev/docs/plugins/prisma/setup#edge-run-times

and it seems to fix the issue, at least it starts and at first glance, everything works.

Is there a downside of this approach? if not, would it make sense to make it the default behaviour?

Letting pothos generate the dmmf seems to make it possible to use pothos with prisma queryCompiler.
