Args are out of sync with the action type for count when creating prisma middeware

[joe-giunti-kiefa]

The arguments in a prisma middleware function are out of sync with the type of the action. If you try to reconstruct the prisma action from the args and action that are in the MiddlewareParams it does not work for count.

let prisma: PrismaClient

//this creates an invalid query because the args in param.args are not valid for params.action=count
//it produces this instead {"args":{"select":{"_count":{"select":{"_count":{"select":{"_all":true}}}}}},"dataPath":[],"runInTransaction":true,"action":"count","model":"User"}
const prismaAction = prisma[modelName][params.action](params.args);

const [, results] = await prisma.$transaction([
  prisma.$executeRawUnsafe(`SET LOCAL request.orgId = '${org}'`),
  prismaAction
]);

The only workaround is to set override this back to aggregate

if (params.action == "count") params.action="aggregate"
//this works now
const prismaAction = prisma[modelName][params.action](params.args);

const [, results] = await prisma.$transaction([
  prisma.$executeRawUnsafe(`SET LOCAL request.orgId = '${org}'`),
  prismaAction
]);
