AI tool Pinaka diagnoses unresolved Prisma bug across four releases without a known fix
Pinaka, an AI-powered root cause analysis tool, was tested against Prisma GitHub issue #29480, an open bug that has persisted across four minor releases from version 7.5.0 to 7.8.0. The bug causes a PrismaClientValidationError when filtering nullable String fields for null values using the PrismaPg driver adapter, while identical syntax works correctly on DateTime and Integer fields. Unlike a previous benchmark, there was no merged fix to validate against, so Pinaka's diagnosis was assessed using behavioral evidence from the codebase itself. The tool identified the root cause as the PrismaPg adapter incorrectly generating 'WHERE field = NULL' instead of the PostgreSQL-correct 'WHERE field IS NULL' for findMany operations on nullable String fields. Pinaka completed its analysis in approximately three seconds, classifying the fault as a framework bug in the adapter rather than user error.
