Error when opening hopper (Polymer)

I paid attention to past issues, the error is similar, I can’t open the hopper, I also can’t create it on the vanilla client.
I believe that further polymer support is needed.

Again, looks to me like you didn't follow the instructions in the confg file.


#
# Uncomment this line if you want to run CopperHopper on a server that works with vanilla clients or clients
# that don't have the mod installed.  CopperHoppers will appear as regular Hoppers on those clients but they
# will function normally.
#
# In order for this to work, you need to also have the polymer mod installed: https://polymer.pb4.eu
#
# polymer-enabled = true
