How to pass admin.firestore.FieldValue.serverTimestamp() to the update() method, using CloudFunction coded in TypeScript

Question

How to pass admin.firestore.FieldValue.serverTimestamp() to the update() method? I want to insert this in an array, like this:

import * as functions from \'         


        

Answer 1

Instead of admin.firestore.FieldValue.serverTimestamp(), you can use admin.firestore.Timestamp.now()

const time = admin.firestore.Timestamp.now();
await amisA.update({
        [`amis.${numeroSender}`] : 
           {
    connaissanceABBA: connaissanceABBA,
    version: version,
    ts: firebase.firestore.FieldValue.serverTimestamp()
  }
});
});

Answer 2

As detailed in the error message you receive, "FieldValue.serverTimestamp() cannot be used inside of an array".

Which is what you do with:

const time = admin.firestore.FieldValue.serverTimestamp();
await amisA.update({
            [`amis.${numeroSender}`] : [time,connaissanceABBA,version]
        });
});

You might have to change your data model and, for example, replace your array by a map, as follows:

const time = admin.firestore.FieldValue.serverTimestamp();
await amisA.update({
            [`amis.${numeroSender}`] : 
               {
        connaissanceABBA: connaissanceABBA,
        version: version,
        ts: firebase.firestore.FieldValue.serverTimestamp()
      }
    });
});
