dtos.spec.ts test passes in Node v18.x, fails in Node v20.x

[sentientforest]

When running npm run test with Node.js version 20.17.0, one of the tests in chain-api/src/types/dtos.spec.ts fails due to a slightly different wording of an error message.

To replicate, use nvm to manage multiple Node.js versions and attempt to build and test in v18 versus v20.

Failure when using Node.js 20.x:

       FAIL   chain-api  chain-api/src/types/dtos.spec.ts
        ● should parse TestDtoWithArray
      
          expect(received).toEqual(expected) // deep equality
      
          Expected: "Unexpected end of JSON input"
          Received: "Unterminated string in JSON at position 16"
      
            71 |   expect(await getPlainOrError(TestDtoWithArray, invalid1)).toEqual(failedArrayMatcher);
            72 |   expect(await getPlainOrError(TestDtoWithArray, invalid2)).toEqual(failedArrayMatcher);
          > 73 |   expect(await getPlainOrError(TestDtoWithArray, invalid3)).toEqual("Unexpected end of JSON input");

The test code expects an exact match on the error message string, and it appears that the wording is slightly different across Node.js major versions.

  expect(await getPlainOrError(TestDtoWithArray, invalid3)).toEqual("Unexpected end of JSON input");
