If you are using Strapi v4 you can do:
module.exports = ({ env }) => ({
connection: {
client: 'sqlite',
connection: {
filename: path.join(__dirname, '..', env('DATABASE_FILENAME', '.tmp/data.db')),
},
useNullAsDefault: true,
debug:true
},
});
in your ./config/database.js
if it does not seem to work, perhaps is not in the right place. It should bein the outer object beneath the useNullAsDefault
