I have started to get alot of “is_singular was called” and “is_page was called” in my debug.log

[31-May-2020 12:10:27 UTC] PHP Notice:  is_page was called <strong>incorrectly</strong>. Conditional query tags do not work before the query is run. Before then, they always return false. Please see <a href="https://wordpress.org/support/article/debugging-in-wordpress/">Debugging in WordPress</a> for more information. (This message was added in version 3.1.0.) in /wp-includes/functions.php on line 5167

On the line 5167 in function.php has this code

        sprintf(
            /* translators: Developer debugging message. 1: PHP function name, 2: Explanatory message, 3: Version information message. */
            __( '%1$s was called <strong>incorrectly</strong>. %2$s %3$s' ),
            $function,
            $message,
            $version
        ),
        E_USER_NOTICE
    );

Anyone could help me in the right direction in how to solve this?

Thank you so much
Best regards
