Watermelondb: undefined is not an object (evaluating 'this.schema.version')

[K4stor]

Hello,

I am trying to get a minimal react native app with watermelon up and running.
You can check my code here https://github.com/K4stor/AwesomeNativeApe

I get the message

console.error: "[DB] Uh-oh. Database failed to load, we're in big trouble", TypeError: undefined is not an object (evaluating 'this.schema.version')

Any Idea what to do ?

[radex]

your schema export is wrong

[K4stor]

OK, what must it look like ?

[FabianEscarate]

hi, i have the same problem.. just change de export part.

export const mySchema [Remove]
export default mySchema [OK]

or when you called, you should be do this.

import { mySchema } from '[Location]'

I think this needs to be fixed in documentation.

[radex]

@finom please send a quick PR correcting the documentation - look at docs-master/ folder

😆😆😆 My sins were that there was a mismatch in my model fields definition and schema definition

It was like this in the model definition:

@field('medicine') medicine

And my schema was like this

{ name: 'my_medicine', type: 'string' },

To correct this: I changed @field('medicine') medicine to @field('my_medicine') medicine

And my sins were forgiven.....🙏🏾🙏🏾🙏🏾

It started working...
