How to avoid using orjson when it is present in environment

Dash Python
1

Hey guys,

have an issue when orjson is in my environment. The app is far too complicated to post here, but some key facts around the problem:

  • using dash==2.8.1
  • issue seems to occur when using either dcc.RangeSlider or dcc.Slider
  • issue only occurs when orjson is present in environment

It is very likely that it has to do with the JSON serialization, some part of the output is:

InvalidCallbackReturnValue: The callback for `[<Output `dashboard_container.children`>]`
                returned a tree with one value having type `Slider`
                which is not JSON serializable.

Now my question, instead of trying to fix the callback output of a very very complicated app, is there a way to avoid orjson being used. That would be a far better quick fix.

Thanks!

Hello @maxschulz-COL,

Welcome to the community!

Dash 2.8.1 is fairly old now. Have you tried with the newer versions yet? We are on 2.11 now. :grin:

That unfortunately doesn’t solve it.
