Can we declare global variables for invoke code in Uipath

[Riya_Bansal]

Hi,
My requirement is I am writing some c# code to fetch values from mongoDb and then passing them as arguments to use those variables in other sequence.

I want to declare those variables as global variables so that the the vales fetch from c# code can be used in any sequence.

Is there any way of doing it. I tried it by using global variables but it is giving me error viz “empty path name is not legal”
Attaching logs for reference:

Hi @Riya_Bansal

Assigning a global variable to arguments in invoke code is not working?

If so you can try assigning to local
Variable and use assign activity next to assign that to global variable

Cheers
