Error converting value {null} to type 'System.Boolean'.

[otium99]

I am using Version 1.3.1 and I am getting the following error with some of the coins in this function:

CoinGeckoClient.CoinsClient.GetAllCoinDataWithId("loopring")

It happens with these coinId's: blox, dmm-governance, origin-protocol, republic-protocol, havven, ethlend, loopring, decred, ravencoin, status, vechain

System.Net.Http.HttpRequestException: Error converting value {null} to type 'System.Boolean'. Path 'tickers[10].is_anomaly', line 1, position 39366. at CoinGecko.Clients.BaseApiClient.d2`1.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at CoinGecko.Clients.CoinsClient.d7.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at CoinGecko.Clients.CoinsClient.d__6.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() at PriceHistories.Form1.d__5.MoveNext()

With CoinId insolar-old it's this error:

Hi @otium99

I added test about your scenario but i can't get this error. You can find test script in my last commit.

Hi @tosunthex

Thank you for the quick reply.

Indeed, I can not reproduce the error in the Test Solution with "loopring", which I have no explanation for, why it's not working in my solution but in the Test Solution.

However, I can reproduce the second error in the Test Solution with some coins. I am running a test at the moment and going through all the coins, which will take a while.

Here are a few examples so far:

Ok. Below you find the complete list out of all the ~7'700 Coins which don't work in the Test Solution. (They all seem to be empty on the CoinGecko Website though)

Then I found out, why my Project is not working with "loopring" and other coins, even though it does work in the Test Solution: The CoinGecko.dll are not the same! I am using the Package Manager from this source https://www.nuget.org/packages/CoinGeckoAsyncApi/ which downloads another CoinGecko.dll than what is produced when I download it from GitHub and compile it myself.

I hope this helps.

Hi @otium99,

Thank you for detailed answer. I just published new version could you download it from Nuget?

[otium99]

Installed the version 1.3.2.0 through NuGet, tested "loopring" and a few other coins from the list and it works fine.

Thank you!
