CS2013

error This call returns no value.

#What it means

This call does something (such as writing a log line) but returns no value, so its result cannot be stored or passed on.

#Typical cause

• Assigning the result of log.info, alert.send or a user function whose body ends in such a call.
• Passing such a call as an argument.

#How to fix it

Call it as a statement on its own line.

#Example

//@chartscript 1
indicator("Log")
const msg = log.info("bar {0}", bar_index)
plot(close)

Fixed

//@chartscript 1
indicator("Log")
log.info("bar {0}", bar_index)
plot(close)
