KarmaTestAdapter.json Causes parsing error.

[gravidThoughts]

Hi Morten!

Love what you have done with this VS extension.

I am having an issue when introducing a KarmaTestAdapter.json file. The following exception is being logged.

When using my karma.conf.js on its own everything works properly. It is a very simple project with all files in the project root folder. Two typescript files. One with a class, the other with the tests for that class.

I simplified the KarmaTestAdapter.json as much as possible.

{
"$schema": "http://MortenHoustonLudvigsen.github.io/KarmaTestAdapter/KarmaTestAdapter.schema.json",
"Disabled": false
}

Interestingly, if I set Disabled to true, no exception occurs and the following is displayed in the the VS output tab [Tests].

[Karma] [Warning] [ktaGlobal] Karma is disabled in KarmaTestAdapter.json

Reading some of the other issues, I tested this against the Karma stack being installed globally in node, and had the same issue.

Originally, the karma.config.js was written in a style using a JS literal object. I changed this to a valid JSON object, and it failed with the same error.

Any ideas?
