Hi @supriyad

Please make sure you have used arguments properly. and there is some value on the value for IN arguments when invoking.

It is likely that when you have invoked GetTransactiondata.xaml you have not passed arguments properly or they do not have any value

Thanks,

can u tell me where particularly??

which arguments can i share zip of my assignment can u correct it ?? or can u provide me any corrected zip ?

See this part in your project

And when passing this make sure WIList has some value in it

Thanks,
Prankur

this part is in main.xaml ???

You are working on Client Security Hash right?

yes right Calculate Client Security Hash.zip (2.0 MB)
can you tell me where to correct this ???

I did those changes which you have suggested me but still giving me same error

Please verify that in GetTransactionData.xaml you are getting WILIst value

Thanks,
Prankur

i am getting this

Can you show me what is this variable1?

yes sure

this is variable1

Did you verify this

in_WIList.Count.ToString

Thanks,
Prankur

hi @PrankurJoshi i put in_WIList.Count.ToString over variable1 but still gives me the same
error

This means there is no value in that argument, please verify that when you extracted value from ExtractWorkItems that variable and arguments are properly assigned.

Firstly Main.xaml must have a variable which has some value

Then make sure you have extracted items in init state

Then pass this to argument when you invoke gettransactiondata.xaml

thanks i will try this
