# Prisma 6 Migration Troubleshooting
|
|
|
|
## Issue: Type error on Bytes field
|
|
|
|
**Error:**
|
|
```
|
|
Type 'Buffer' is not assignable to type 'Uint8Array'
|
|
```
|
|
|
|
**Solution:**
|
|
Replace Buffer operations with TextEncoder/TextDecoder or use Uint8Array directly.
|
|
|
|
## Issue: Migration fails with duplicate key
|
|
|
|
**Error:**
|
|
```
|
|
ERROR: duplicate key value violates unique constraint "_CategoryToPost_AB_unique"
|
|
```
|
|
|
|
**Solution:**
|
|
Implicit m-n tables may have duplicate entries. Clean data before migration:
|
|
```sql
|
|
DELETE FROM "_CategoryToPost" a USING "_CategoryToPost" b
|
|
WHERE a.ctid < b.ctid AND a."A" = b."A" AND a."B" = b."B";
|
|
```
|
|
|
|
## Issue: NotFoundError import fails
|
|
|
|
**Error:**
|
|
```
|
|
Module '"@prisma/client"' has no exported member 'NotFoundError'
|
|
```
|
|
|
|
**Solution:**
|
|
Remove NotFoundError import, use P2025 error code checking instead.
|
|
|
|
## Issue: Reserved keyword compilation error
|
|
|
|
**Error:**
|
|
```
|
|
'async' is a reserved word
|
|
```
|
|
|
|
**Solution:**
|
|
Rename field in schema with `@map()` to preserve database column name.
