What did you expect to happen?

[Explain what you expected to happen after performing the previously described steps]

Please also provide the shop setup that you are trying to use.

Also your log contains errors pointing to this issue, please make sure that the player that owns the shop logged in at least once and that you have player data caching enabled. Otherwise you might need to use a different Economy plugin or a custom Essentials Economy adapter that fixes that issue.
