Error on getting/setting property : Value cannot be null

[fx.practic]

Hello.

I am experiencing error

Error on getting/setting property 'My_Parameter' for NinjaScript 'My_Strategy/-1': Value cannot be null.
Parameter name: Strategy 'My_Strategy/-1': no such parameter 'My_Parameter'

while optimization.

It happens for each parameter with attribute [Browsable(false)].

Am I doing something wrong?

Hello fx.practic,

Can you provide the full code for the input?

Is there a default being set for the input? If so, what is the default?

Attached is a test where I have made two inputs, one with [Browsable(false)] one without. I am not able to reproduce.

Are you able to reproduce the error with the test script attached?

Hello, Chelsea

Please, look video below.
I got same error message with Your script while optimization:
Error on getting/setting property 'TestInput1' for NinjaScript 'BrowseableFalseInputTest/-1': Value cannot be null.
Parameter name: Strategy 'BrowseableFalseInputTest/-1': no such parameter 'TestInput1'
Error on getting/setting property 'TestInput1' for NinjaScript 'BrowseableFalseInputTest/-1': Value cannot be null.
Parameter name: Strategy 'BrowseableFalseInputTest/-1': no such parameter 'TestInput1'

In my script I use both old and modern setters approach with same result.
Only [Browsable(true)] let optimization start.

Hi fx.practic,

I overlooked that the [NinjaScriptProperty] attribute was still applied. This need to be removed.

The [Browsable(false)] attribute hides the property from the UI. The [NinjaScriptProperty] attribute if removed will prevent the property from showing in the overloads and list of optimizable inputs.

An object with [NinjaScriptProperty] applied must be Browsable in the UI to be optimized over.

This helps, Thank You, Chelsea!
