Class UnexpectedValueException not found

[vikram6]

I'm seeing the following error when running certain wp cli commands -

PHP Fatal error:  Uncaught Error: Class "WpOrg\Requests\UnexpectedValueException" not found in wp-includes/Requests/src/Iri.php:726

I believe this bug was introduced recently in this commit - https://core.trac.wordpress.org/changeset/56835. UnexpectedValueException is missing the backslash \ and hence PHP is trying to find it in the WpOrg\Requests namespace instead of the global namespace. The lines of code that are referencing UnexpectedValueException should be updated to the following -

throw new \UnexpectedValueException();

Full stack trace -

More details -

• WordPress version - 6.4.2
• WP CLI command - wp search-replace foo bar --regex --skip-plugins --skip-themes
• The database needs to have a certain format of serialized data to reproduce this but I'm not exactly sure what that format is.
