[Rspamd-Users] Script attempted to access nonexistent global variable 'cjson'

[C. Bernard]

Re-hi

Any hints what I shall do, to get rid of that message (below - in  
other message)? (It's still here).
Remove all redis entries? (Clear or Flush or something, if such thing exist?)

Thanks

Hi all

for a few weeks now, I get every minute in the log:
2020-01-25 17:53:00 #23402(controller) <ndniuo>; lua; neural.lua:1142:
cannot exec invalidate script in redis: ERR Error running script (call

'cjson'

Any idea what I could do to make that go away?
Too old Redis, it is unsupported - please bring it back to the crypt
where you have taken it.
Dec 26 15:17:39 beastly pkg-static[80755]: redis-5.0.7_2 installed

[root at beastly /var/log/rspamd]# pkg ver -v | fgrep redis
redis-5.0.7_2                      =   up-to-date with index

redis ist newest stable.

First time the err occurs:
2020-01-02 08:14:15 #84377(controller) <z7rj9g>; lua; neural.lua:1142:
cannot exec invalidate script in redis: ERR

So it does not seem connected to update of redis or its ancientness..
Any other idea?

Thanks
