that looks like an API key you shouldn't have leaked

Sinkarq•11mo ago

it's for the local emulator I guess it isn't a big deal

Jimmacle•11mo ago

i don't see an AnyAsync anywhere unless i'm blind

here it is

Jimmacle•11mo ago

does this part of the code you posted work?

        var usedEmail = await _usersRepository.AllUsers()
            .FirstOrDefaultAsync(x => x.Email == normalizedEmail);

        var usedEmail = await _usersRepository.AllUsers()
            .FirstOrDefaultAsync(x => x.Email == normalizedEmail);

Sinkarq•11mo ago

yes, as expected but when I try to use AnyAsync it throws exception

Jimmacle•11mo ago

that suggests the db provider doesn't implement a translation for AnyAsync i've never used cosmosdb so i wouldn't know for sure

Angius•11mo ago

What db are you using, and what does _userRepository.AllUsers() return?

Jimmacle•11mo ago

it returns _databaseContext.Users.AsQueryable();

Sinkarq•11mo ago

CosmosDB, it returns IQueryable from the DbSet of the Users

Jimmacle•11mo ago

bad way to write a repository but that's another topic

Angius•11mo ago

Well, the repository at least doesn't do anything special, it's just useless passthrough methods

Sinkarq•11mo ago

right now you are both right, I put the repository so if ef core (first time tryting it for cosmosdb) makes the developer experience bad I would switch to the default CosmosDb SDK EF Core DBContext implements the repository pattern to some extend by itself but that's another topic

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
