ClashOfClansException on ClashOfClansApi.Clans.GetAsync(ClanTag) about clashofclans

[tparviainen]

I just tried exactly the above repro steps and I wasn't able to repro.

Clans API has two GetAsync methods:

Task<SearchResult> GetAsync(QueryClans query);
Task<Clan> GetAsync(string clanTag);

The latter one (GetAsync(string clanTag)) is the one where you provide a clan tag and it gives the clan information. The former one (GetAsync(QueryClans query)) is where you provide a QueryClans object that has properties to filter the search results. If QueryClans is provided empty in API call then Supercell API returns a bad request to caller with next information:

Content: {"reason":"badRequest","message":"At least one filtering parameter must exist"}

That is a valid error because QueryClans must always have at least one filtering criteria defined.

If you could share a sample solution with this problem that I can just open in VS and get into the state, it would be great for investigating.

Thank you for your reply. Attached is an example project which causes the exception when run.

Thanks for providing the project to investigate this more. I found the issue causing this behavior. It seems that net461 does not URL encode hash (#) character automatically whereas netcoreapp2.2 implementation of HttpClient will do it.

I changed the implementation of the library to URL encode hash character always and now it seems to work properly also in net461. I will push a commit soon to fix this issue and release 3.0.5 version of the NuGet package with the fix.

Thanks for reporting this issue!
