eval 执行 lua 报错 user_script:1: @user_script: 1: Lua redis() command arguments must be strings or integers

[UnrealEngine]

ERR Error running script (call to f_a08c9c69b7c07ae2485190873b90d128a23e502d): @user_script:1: @user_script: 1: Lua redis() command arguments must be strings or integers

报错来源自

Connection->command('eval', array('return redis.call('exists',KEYS[1])<1 and redis.call('setex',KEYS[1],ARGV[2],ARGV[1])', 1, 'cache:8e3a74c63406753fa072630e7112b312ffc42b99', 0, 60))

已经懵了，问其他同事也不知道原因，只能找万能的 v 友了

试一下 tonumber(ARGV[2])
