Build failure due to post-processing JSON

I ran into this issue with the current build. @skalee is post processing JSON a new process?

Postprocessing with json_pp is my solution to sanitize malformed JSONs. In some cases it is not capable to do so. However, these errors do not cause a build failure (exit status is 0). They are printed to console though.
