You would have to improve the code quality of the application, which does not seem
to do correct error handling or transaction management.

That error means that the *previous* statement (or one of the statements earlier in
the same database transaction) has caused an error. In PostgreSQL, that means that
the transaction is aborted, and the following statements until the end of the
transaction will receive the error you experience.

So one of the following must be the case:

- the previous statement caused an error, but you didn't detect or handle that

- the previous transaction run on the same database connection caused an error,
but you forgot to run ROLLBACK
