Redis invalid TTL/expire value
ERR.*invalid expire time|ERR.*timeout.*negative
Fixes
- 1.Ensure TTL is a positive integer (seconds for EXPIRE, milliseconds for PEXPIRE)
- 2.Check that the value isn't NaN or undefined before passing to expire command
- 3.Use EX (seconds) or PX (milliseconds) option with SET for atomic set+expire
