i have code here:

the "MONGODB_URI" showed above already put into heroku's app
config as the 'key' and there is a paired 'value'. so the uri
is to extract the value which is to use for app to establish
mongodb connection.
and above code with error msg here: Error: `getenv` cannot be

That part of the code is probably fine.
Basically you have to be careful that:
auto uri = environment.get("MONGODB_URI");
Isn't being executed during compilation.
Stuff that typically cause this is anything that initializes a
variable.
Globals:
shared Foo foo = Foo(...);
Class fields:
class Foo {
Bar bar = Bar(...);
}
yes, then should be this?
struct Camera{
@name("_id") BsonObjectID id; // represented as "_id" in the
database
string brand;
string model;
}
the structure is mapping of database field structure. how to
resolve?
