databases.listDocuments is returning null
TL;DR
Issue: developers are experiencing 'databases.listDocuments' returning null when trying to retrieve patient data based on a given user ID. They are unsure why this is happening, even after creating a relationship between patient collection and appointment.
Solution: The code snippet provided reveals the use of 'Query.equal' with array brackets around 'userId'. Developers should remove the square brackets to properly query the database. Update the code to look like this:
```
const patients = await databases.listDocuments(
DATABASE_ID!,
PATIENT_COLLECTION_ID!,
[Query.equal('userId', userId)]
)
```
