The documentation and the error message explain the issue.

"there is no unique or exclusion constraint matching on the CONFLICT
specification"

"The optional ON CONFLICT clause specifies an alternative action to raising
a unique violation or exclusion constraint violation error."
-https://www.postgresql.org/docs/current/sql-insert.html

You have an index, but it is not unique. With partitioning, you cannot
create a unique index on a column that is not contained by your partition
key. So, you need to re-write to skip the use of ON CONFLICT I expect.
