I am getting the following error while debugging the code. Basically I have an issue where I cant deserialize the response, see this [How to run multiple search templates using NEST](https://discuss.elastic.co/t/how-to-run-multiple-search-templates-using-nest/334933) In frustration i pulled the github code and referenced it in my project to see what is going one. Got the below error. It says I should open a bug. I don't even know what bug to open. These serializers/formatter makes no sense to me. ![image](https://us1.discourse-cdn.com/elastic/original/3X/2/5/2565b85a99fd309b16abc0c65d87025c4192c2fb.png) ---

Hi @Jacques_du_Plessis, Thanks for giving details of your investigation. Which version of the .NET NEST client are you using? Can you raise a [Github bug issue](https://github.com/elastic/elasticsearch-net/issues/new/choose) for the respective version with the details of the error? ---

I am using NEST version 7.17, initially I thought it had todo with the ES version I was running. I ran ES version 8.2 and the NEST version 7.17, but then I down graded my ES version to also 7.17 but the issue persisted. I will open a bug, any chance you can help with a work around for my previous question? (The link that I sent.) The only thing i can think of is to send multiple requests. ---
