Hi, can you please provide me with information if Swashbuckle.AspNetCore 7.3.1 is compatible with System.Text.Json 9.0.0? With version 8.0.5 it works fine, but after upgrading I get an error. I couldn't find it in documentation unfortunately. Code example to reproduce is in attachments

You're using net7.0, which has not been in support since May 2024, and is not supported by Swashbuckle 7.x.

Target net8.0 or net9.0 and see if that resolves your issue.

Alternatively if you need to stay on .NET 7, which is not recommended, then use an older version of Swashbuckle that targets net7.0 along with a compatible version of System.Text.Json.

Thank you. I used Swashbuckle.AspNetCore 6.9.0 and also had this issue when upgraded System.Text.Json to 9.0.0. So, I see - the option is to upgrade to .net8, 9 or use Swashbuckle.AspNetCore 6.9.0 with System.Text.Json 8.5.0
