PDO::prepare (...) not compatible with Doctrine

[daniil_m]

Hello.
Trying to update my ESPO from quite old version 5.4.5 and my execution envernoment accordingly.
But meet the issue.

After update php to 7.3 got error bellow:

"FastCGI sent in stderr: PHP message: PHP Fatal err: Declaration of PDO::Prepare(string $query), array $options = []): PDOStatment|false must be compatible with Doctrine\...\Connection::prepare($prepareString)"

As I can see application code enherits Doctrine base class not corretly. Is it version missincronisation of Doctrine library and Application?

After some experiments I succeeded to update to ver 5.7.11.
The environment I have used:
- php 7.1.14
- 10.11.2-MariaDB
