App seems to crash on validation of composer file

[jaap]

I have a repo with quite a large history which also contains tags well before it was a composer package.
It seems that the Heroku app is crashing with a Composer\Json\JsonValidationException on validating composer.json files from these older tags.

Is my conclusion right that repo's with a tagged released containing a non-working composer.json would fail the server to start?

To further illustrate, here an example of the composer file in where it seems to crash on;
