CSV Writer Error: cannot open the connection ERROR CSV Writer

KNIME Server
1

I have installed a KNIME server and was trying execute a KNIME workflow. Per workflow, I was trying to write a csv (around 150k rows and 130 columns) using CSV writer node. But getting error:

Error: cannot open the connection
ERROR CSV Writer 0:20 Execute failed: Error writing request body to server

I looked at the server log:
BELOW are the few lines of the server ERROR LOG:

2020-04-20 08:53:33,413 : ERROR : KNIME-Worker-44-CSV Writer 2:20 : : Node : CSV Writer : 2:20 : Execute failed: Software caused connection abort: recv failed
java.net.SocketException: Software caused connection abort: recv failed
at java.net.SocketInputStream.socketRead0(Native Method)

I found the error. In output location of csv write node, I wrongly wrote ‘/’ instead of ‘’
