## Fix
### Prisma Client
- [MaxListenersExceededWarning: Possible EventEmitter memory leak detected. #6584](https://github.com/prisma/prisma/issues/6584)
- [Netlify Functions deploy fails with Prisma because of size problems, Prisma deploys with 2 QE binaries
#6503](https://github.com/prisma/prisma/issues/6503)
If the issue persists when deploying to Netlify, we recommend manually clearing Netlify's build cache from the ‘Deploys’ menu. Under ‘Trigger deploy’, you’ll see ‘Clear cache and deploy site’.
