I have rebased this to 5.1 as it is a new feature.

[laoneo]

Please wait till 5.1 is fully up to date with 5.0.

this pr is not a feature it'a a bug fix
i'm not adding any new endpoint here i'm just fixing response HTTP 500
see https://docs.joomla.org/J4.x:Joomla_Core_APIs

For me it looked like a new feature. Next time it would help when you update the pr description with the link.
