minor fix

[dsbe-ak]

I got the error "Typed property must not be accessed before initialization" which was fixed by setting additionalParameters = ''

[dsbe-ak]

Are you happy to merge/release?

Thanks for the fix, why not make it optional?

private ?string $additionalParameters;

[dsbe-ak]

I think the issue here is, that additionalParameters is undefined (null != undefined), therefore I added a default value (so setting an empty string seemed to me the easiest way here).

Sure, but why not using as initial value NULL instead of an empty string? @dsbe-ak

[dsbe-ak]

In my opinion it is not necessary to change the type to solve this error. Empty string as default value looks fine by me.

From my point of view empty string and null are to different states. And null is more better for a state which describes it is not initialized or used.

But anyway, I will merge it and create a new release

Thank you!
