blazor wasm throwing deserialization exception when published

I have a Blazor WASM application that I publish to a server where it's run as an IIS site.

I've just converted it to .NET 8 and in DEBUG and RELEASE modes it executes just fine on my machine in Visual Studio.

However, when I publish it either as a self-contained app or as a portable app then I get the following exception when it runs one page in the site:

Digging into the method that generates the error, I have the following lines of code:

JsonSerializerOptions options   = new() { PropertyNameCaseInsensitive = true };List<KeyValuePair<string, string>> items   = JsonSerializer.Deserialize<List<KeyValuePair<string, string>>>(data, options)!;

If I include the following line:

Console.WriteLine($"data: '{data}'");

And inspect this in the Browser's console, then I see that data is as I would expect, namely:

[  {"key" : "some key","value" : "some value  },  {"key" : "some key","value" : "some value  },  ... etc]

If I capture that exact JSON and execute the following in LinqPad

List<KeyValuePair<string, string>> list = JsonSerializer.Deserialize<List<KeyValuePair<string, string>>>(dataFromConsole, options)!;

then it works absolutely perfectly.
