In a custom plugin I need to invalidate a Kong cache entry. When I use
kong.cache.invalidate_local("thisisastring")
I get error
key must be a string
stack traceback:
[C]: in function 'error'
/usr/local/share/lua/5.1/kong/cache/init.lua:226: in function 'invalidate_local'
I'm using Kong 2.7.0.
https://github.com/Kong/kong/blob/2.7.0/kong/cache/init.lua#L226
What is wrong?
