I'm using Microsoft storage emulator for development and in concrete, the method that gives me an error is the exists(), the error is a null pointer exception.
Looking deeply in the library, I was able to find that it was requesting a couple of headers, then I notice that the endpoint response from azure blob storage is different than from azure storage emulator:
From the emulator:
curl -G http://127.0.0.1:10000/devstoreaccount1/default?restype=container -v -H 'x-ms-version: 2019-07-07'

As you can see, there are a couple of headers missing in the storage emulator.
Is there a way to get around this ?
how recommended it is to wrap the exists() method on my own just to be able to use the development storage emulator ?
Versions:
- StorageEmulator: 5.10
- SDK: 12.4.0
- Language: Java
Thanks.
Note: I have removed information as tls and ips from the curl responses.
