"Cannot read property 'dmmf' of undefined"

[BaptisteCayrier]

Hi, I tried to use you tool PrismaSelect (which looks so usefull!) but I faced a little issue:

Here is my code:

import { PrismaSelect } from '@paljs/plugins';

[...]

const select = new PrismaSelect(info, { dmmf: undefined }).value;
return prisma.user.findMany({
     ...select.value,
});
```javascript
which lead to the error "Cannot read property 'dmmf' of undefined".

After some investigation I found the origine of the problem.
In the file `node_modules/@paljs/plugins/dist/plugins.cjs.development.js` on the declaration line 365:
```javascript
{
    key: "dataModel",
    get: function get() {
      [...]

      if (...) {
        [...]
      } else {
        var _require = require('@prisma/client'),         // <- this line
            Prisma = _require.Prisma;                            // <- and this line

        if (Prisma.dmmf && Prisma.dmmf.datamodel) {
          models.push.apply(models, Prisma.dmmf.datamodel.models);
        }
      }

      return models;
    }
  }

I printed _require and _require.Prisma is undefined:

_require =  {
  prismaVersion: {
    client: '2.5.1',
    engine: 'c88925ce44a9b89b4351aec85ba6a28979d2658e'
  },

      [Object], [Object]
    ],
    schema: { enums: [Array], outputTypes: [Array], inputTypes: [Array] }
  },
  PrismaClient: [class NewPrismaClient]
}

One possible fix could in this same file could be:

[...]
else {
        var Prisma = require('@prisma/client');        // <- this line

        if (Prisma.dmmf && Prisma.dmmf.datamodel) {
          models.push.apply(models, Prisma.dmmf.datamodel.models);
        }
} 
[...]

However, I think this is generated code and the correct fix is probably to be done in https://github.com/paljs/prisma-tools/blob/main/packages/plugins/src/select.ts#L78

From

      const { Prisma } = require('@prisma/client');

To

      const Prisma = require('@prisma/client');

I hope everything is well explained and thanks in advance for you to look at it :)

you need to upgrade prisma to the last version or down our plugin to version 2

[BaptisteCayrier]

Hi, thanks for your answer! Everything working as expected now! :)

I didn't saw this information anywhere on any Readme, maybe you could add it to make sure nobody face this issue again. :)

[AhmedElywa]

you will get this info on the release notes
