D10 TypeError: htmlspecialchars()

Hi friends! I'm Diana!
I am working in a personal module, I use Drupal 10 i 8.2 PHP.
The past days I made a migration of Drupal 7 only with .yaml and API Migrate of Drupal, because I can't use Composer or drush because the hosting is a sh***.
I have an error in the next part of the website: ..../admin/reports/dblog

When I execute this url, the message is:

TypeError: htmlspecialchars(): Argument #1 ($string) must be of type string, array given in htmlspecialchars() (line 432 of core/lib/Drupal/Component/Utility/Html.php).

The problem is that in the new module I wrote ...'Fecha seleccionada: @fecha', Array... but now I deleted this part of code, and the error persist.

I made trunk in a cache tables of DDBB.

I don't know if this problem is from the prehistorical migration, from the new module or from both.

Please help.
ThankU
