My workflow reads a CSV and then outputs to a column each time the workflow is completed. After about 3 cycles it paused so I pressed restart in UIpath. Instead the workflow was hanging then did not restart. After manually restarting I got the message
Read CSV: Value cannot be null.
Parameter name: source
When I checked the file it was 0kb with the same name and opening it causes the excel error message “Sorry we couldn’t open the file C://…”
Luckily no important data was lost and I can rebuild the file but seems like a potentially problematic bug
For further context I have been running this same process daily with this bot for almost a year and this is the first time this has happened
Hi @Zephyr ,
Can you provide additional details to allow us to investigate this:
- Excel package version
- Where are you outputting the results? To an additional CSV? The same CSV?
- What do you mean by cycle?
- Were there any changes from the last time this worked correctly? (i.e. package version, Studio, etc)
- Was the CSV file populated?
