msbuild: Build fails when try to process the bundleconfig.json

We have CI setup in VSTS and all of a sudden. Even on previously successful builds.

The build started failing when it tries to process the bundleconfig.json I can confirm we don’t have any changes in that file and previous builds were successful. The build fails at the same point even if I try to rebuild branches where it was successful.
