What could be the problem
const result = await this.database.listDocuments(this.databaseId, this.questionCollectionId, ['language=en'])
Without ['language=en'] it returns all elements, but I only need the filter.
TL;DR
Developers are facing issues with an invalid query in their code when trying to filter results by language. Removing ['language=en'] returns all elements but they're seeking a solution to effectively apply the filter.
