Cannot read property initializeJSI of null

I follow the installation and setup steps and I got this error.

-babel.config.js:

module.exports = {
presets: [
'module:metro-react-native-babel-preset',
'@babel/preset-typescript',
],
plugins: [
['react-native-reanimated/plugin'],
[
'babel-plugin-root-import',
{
rootPathPrefix: '~',
rootPathSuffix: 'src',
},
],
'babel-plugin-transform-typescript-metadata',
['@babel/plugin-proposal-decorators', { legacy: true }],
['@babel/plugin-proposal-class-properties', { loose: true }],
['@babel/plugin-transform-private-methods', { loose: true }],
['@babel/plugin-transform-private-property-in-object', { loose: true }]
],
};

• index.ts:

import {Database} from '@nozbe/watermelondb';
import SQLiteAdapter from '@nozbe/watermelondb/adapters/sqlite';

import schema from './schema';
// import migrations from './migrations';
import Treatment from './treatements';
import Visit from './visits';

const adapter = new SQLiteAdapter({
dbName: 'appv3',
schema,
// migrations,
jsi: true /* Platform.OS === 'ios' */,
onSetUpError: error => {
console.log(error);
},
});

export const database = new Database({
adapter,
modelClasses: [
Treatment,
Visit,
// and so on
],
});

• Schema:

import { appSchema, tableSchema } from "@nozbe/watermelondb"
import { tableName } from './table-name';

const schema = appSchema({
version: 1,
tables: [
tableSchema({
name: tableName.VISITS,
columns: [
{ name: 'name', type: 'string' }
],
}),
tableSchema({
name: tableName.TREATMENTS,
columns: [
{ name: 'name', type: 'string' }
],
}),
],
});

export default schema;

Try jsi: false when you're using new arch. Will be added support to new arch soon.
