Hi there everyone.
I kindly need assistance, I am busy running a process in Uipath and I am having issues with one section that gives me the result “Write Line: Object reference not set to an instance of an object”. Please kindly view, below, the screenshot that shows the text filled in, in the write line text box.

What do your invoke arguments look like?
@wendy Your variable value is having null value so you are getting this error.

ok, that narrows it down. Where did you declare the original flatfileDT? That may be the problem. try doing a write line with the same coding straight after it was created and see if you get the same error

The FlatFile you have initialised here is an array of strings, where are you converting that to a datatable (FlatFileDT)? If you aren’t converting it correctly then that is where the issue lies
@wendy did you get this one resolved?
Hi AndyD
I was booted out of where I was working (the remote desktop at work) so a trouble shooting is happening.
Thank you for your assistance. I will solve the issue .
