Call to GetParameters returns NT_GET_PARAMETERS failed. 0x80040221

Good morning,

I am getting the error NT_GET_PARAMETERS failed. 0x80040221 when calling SLProtocol.GetParameters. The line of code that is failing is

object[] parameterValues = (object[])protocol.GetParameters(new int[] { Parameter.getworkflows_responsestatuscode, Parameter.getworkflows_responsecontent });

The actual message is

2026/05/13 08:09:42.484|SLManagedScripting.exe|ManagedInterop|ERR|-1|8936|15|NT_GET_PARAMETERS failed. 0x80040221

My intention was to combine the several calls to protocol.GetParameter in my QActions into a single one. What could I be doing wrong?

Thanks and regards

Hi Anderson,

Can you try by changing the type to uint[] cf. the examples on GetParameters?

Hi Pedro,
thanks for the quick response. I should have noted uint on the documentation page.
The exception is no longer being thrown after replacing int[] with uint[].
Thanks again
