Welcome to the UiPath Community @jegadeesh_Babu

This error comes when the datatype is invalid for the source is invalid.

Suggest you to check the dictionary’s datatype of the value component and make it string

Also print the value before this assign to see the value is being correctly generated, there might be something wrong in there too.

Always go about such issues by debugging it and checking the locals panel for all the values at the time of error

Hope this helps

Do you really have a dictionary named dictionary? That’s a bad idea.

Rename your dictionary to something that’s not likely to be a reserved word or other type of object.

Welcome to forums

For adding items to dictionary, check below for your reference

Adding items to a dictionary

If you’re working with dictionaries, I’d strongly suggest installing Microsoft.Activities.Extensions package - there’s a couple of very useful activities for them in there that will make your life easier. Or you could use InvokeMethod, since .Add is void and thus cannot be used in Assign. Regards.

Hope this may help you

Thanks
