No stack trace = no valid issue.

Hi,
I had the same issue today. It seems version 106.2.1 works without the exception however latest stable 106.6.9 gives
Exception thrown: 'System.ArgumentException'

[alexeyzimarev]

Well, guys, you are having the issue and not even give me the code or stack trace. How do I suppose to help you? I will reopen the issue once you submit it properly, with the information that is following the contribution guidelines.

[lymims]

I've give codes and screen shot, but it is folded:

[alexeyzimarev]

Paste the stacktrace and the code. One line is not enough.

update:

work fine in vs2017, throw exception in vs 2019.

var client = new RestClient("https://api.trello.com");
var request = new RestRequest("/1/actions/592f11060f95a3d3d46a987a");
var content = client.Execute(request).Content;

Hi,
I have the same setup as well VS2019. One clue that I found when request is created with latest version using have null values for serializer.

Then when response get serialized, I get same exception as lymims commented out

Also call stack as

I'm getting the same exception and stacktrace as above.

Also getting the same issue. Not sure if this is connected but repsonse contain: ' , i.e. (apologic)

Any reason why this issue is closed?

[alexeyzimarev]

Because I asked for the stack trace several times and nothing happened. Then I closed it. Then people still failed to give me a proper stack trace and posted a lot of screenshots that are really hard to read instead. It is a very easy task to copy-paste the stack trace. If the issue is correctly formulated, following our contribution guidelines, it will be considered.

In my case, the stacktrace looks like this:

(RestSharp v106.6.10, VS2019 latest preview, running a Xamarin.Forms Android app)

edit: I think it worked with version 106.6.9, but I have to retest to confirm it
edit2: doesn't work with 106.6.9, trying again with 106.5.4
