Hey @PepeMax, a minor change required for your query.
I suggest you to use the below query for accurate results.
const query = await strapi.db.query("api::appel.appel").findMany({
where: {
$not: {
espace: null,
}
},
populate: {
espace: {
where: {
numero: 10
// numero: { $eq: 10 } Other way to use where query for the above
}
},
file: {
select: ['name', 'url']
}
},
});
