Invalid Document Reference. Document References Must Have An Even Number Of Segments

I am querying a collection for documents using below code. Document names are same as device names. The device name is passed to the document from an API I am getting an error when

Solution 1:

try this

response.body().get(finalI).getDeviceName().toString().replace("/","_")

Solution 2:

The simplest method I can think of, is before you add the data to the database to find that forbidden / symbol and replace it with an allowed one, let's say - (minus).

String deviceName = response.body().get(finalI).getDeviceName().replaceAll("/", "-");

And then simply use in your reference like this:

firebaseFirestore.collection("Mobiles").document(deviceName);
