Error occurred during query execution: cause: Some(WrongType...

I am busy switching from sequelize to prisma. Most of it works, but there’s a custom data type of interval that we’ve been using in sequelize. We use this package.

When I ran prisma instrospect it generated type String? which is obviously wrong.

I get a pretty useless error message when I run into this.

 Error occurred during query execution:
ConnectorError(ConnectorError { user_facing_error: None, kind: QueryError(Error { kind: FromSql(7), cause: Some(WrongType { postgres: Interval, rust: "core::option::Option<alloc::string::String>" }) }) })
    at PrismaClientFetcher.request (/node_modules/@prisma/client/src/runtime/getPrismaClient.ts:1223:15)
    at processTicksAndRejections (internal/process/task_queues.js:82:5)

My model has over 100 fields on it and I had to figure out which field was causing it by process of elimination.

Reading the error message again after figuring the issue out I saw “Interval” was in there, but it was not clear that it’s a data type of Interval causing it, nor did it say which field in my selection was causing it. I’d suggest some better error message in general when a specific selection fails.

I’d also like to request that Prisma can handle Interval data types for postgres

Interval types are not supported at all (see https://github.com/prisma/prisma-client-js/issues/917 for a request to fix that), so whatever is introspected or any queries run against these fields have undefined and probably broken behavior.

@janpio here’s the issue as requested: https://github.com/prisma/prisma-client-js/issues/917

I’ll rename this one to match the error handling
