Hi,

This error occurs if you have shared mailboxes configured, but not a map for sharing with "anyone". Dovecot then tries to perform a SQL query for something that doesn't exist and logs this error message.

Error: acl: dict_iterate() failed: sql dict iterate failed for shared : Invalid/unmapped path

There's a 14 year old discussion that talks about adding a dummy table and map to prevent the error:

I'd rather add this table since I'm not using sharing to anyone, is there a way to prevent dovecot from making this query?
