Error generating typescript client System.Int64' cannot be converted to type 'System.Int32

See original GitHub issue

Environment - ASP.NET Owin.

After upgrading NJsonSchema.CodeGeneration ^ NJsonSchema.CodeGeneration.TypeScript to 10.1.11 and NSwag.CodeGeneration.TypeScript 13.3.0 generator throws error. On any method (tried to mark all with [OpenApiIgnore], and find “bugged method” but without success)

NJsonSchema.CodeGeneration 10.1.5 and NSwag.CodeGeneration.TypeScript 13.2.3 version working fine.

Any clues how to fix it?

As I can see, it’s change in DotLiquid that introduced by
commit 7c168d18b4ec5665076e03cde8152ebceecb1985 Author: David Burg daviburg@microsoft.com Date: Tue Feb 25 13:14:34 2020 -0800

Support integer values for numbers beyond the range of 32 bit integers but within the RFC allowed 64 bit integers.

at Context.cs Contect class in function private object Resolve(string key, bool notifyNotFound = true)

Old code parses integers in such way:

   match = IntegerRegex.Match(key);
            if (match.Success)
                return Convert.ToInt32(match.Groups[1].Value);

new code parses integers and return long

           // Integer.
            match = IntegerRegex.Match(key);
            if (match.Success)
            {
                return Convert.ToInt64(match.Groups[1].Value);
            }

after that it leads to exception in Strainer.Invoke due to dynamic “tab” filter invocation because it has signature {(, System.String Tab(DotLiquid.Context, System.String, Int32))}

The workaround is to downgrade DotLiquid to 2.0.314
