Unable to string.Format a C# multiline verbatim string when escaping curly braces

this one helps. You are using the C# string interpolation special character "$", however, you are using positional parameters in your template.
It should be:-
String s = @"{{ ""ver"": ""1.0"",""userId"": ""{0}""}}";

String.Format(s, "1234").Dump();
var userId = 1234;

String s = $@"{{ ""ver"": ""1.0"",""userId"": ""{userId}""}}";
var x = new
{
    ver = "1.0",
    userId = "1234"
};

var s = JsonConvert.SerializeObject(x);

Escaping arguments for string.Format in a C# multiline verbatim string

may help you . The problem is the open and close braces. You need to quote those, or Format will think you're begining a parameter specifier.
string template = @"   
          {{   
            argument1   = ""{0}""; 
            argument2   = {1};   
          }}";

it should still fix some issue It seems that you have missed escape for the products and query objects:
$@"{{
    ""name"":""{taskName}"",
    ""products"": [
        {{""product"": ""ndvi_image"", ""actions"": [""mapbox"", ""processed""]}},
        {{""product"": ""true_color"", ""actions"": [""mapbox"", ""processed""]}}
    ],
    ""recurring"":true,
    ""query"": {{
        ""date_from"": ""{dateFromString}"",
        ""date_to"": ""{dateToString}"",
        ""aoi"": {polygon}
    }},
    ""aoi_coverage_percentage"":90
}}";

I think the issue was by ths following , You should use {{ and }} when you need a single curly brace. From the docs:

Get string enclosed in curly braces with escaping using RegEx

help you fix your problem I want to extract text enclosed inside curly braces. But the complication is that any closing curly brace } with preceding back-slash \ should be included as well in the result. , You may use
var content = '{abc123*-\\}}{sdf}';
var regex = /\{([^\\{}]*(?:\\[^][^\\{}]*)*)}/;
var firstMatch = content.match(regex); // results 'abc123*-\\'
if (firstMatch) {
  console.log(firstMatch[1]);  // => abc123*-\}
}
