Possible Solution
Better handle this state so one knows what is the problem.

Think it does come from this commit: https://github.com/api-platform/core/pull/4013

[mehdibo]

I'm having the same issue, any solution?

[croftman]

Same here

[jacka33]

Remove these lines if ('schemas' === $key) { if ($value) { ksort($value); } }

[alanpoulain]

Fixed with https://github.com/api-platform/core/pull/4051. Please wait for the next patch release.
