Why does the gRPC response not show fields with false boolean value?

I have a gRPC API with a method which returns a field with a boolean value as the response. When I make a request to this gRPC method using Postman, the field is not shown in the response when the boolean is false. It only shows up when the value is true.
Is this behavior expected or is this a bug or do I have to change some setting to make the field appear even if it is false?
I have also tried out different gRPC clients but those do show the boolean field with the false value.
Thanks in advance!

@octopus235 No, this is definitely a bug. However, it’s working fine for me:

Can you report this in our GitHub issue tracker with the steps to reproduce this issue?

Of course, I will do that. Thank you!
