Original GitHub issue: https://github.com/Seldaek/monolog/issues/1959

Monolog version 2

In the class Logger, in version 2, line 383, we have

'datetime' => $datetime ?? new DateTimeImmutable($this->microsecondTimestamps, $this->timezone),

but class DateTimeImmutable was not imported. We need to add a use statement or use \DateTimeImmutable.

Right now, in our project, we are getting the error

PHP Warning:  include(/opt/speakap/versions/releases/20250317180438/vendor/composer/../monolog/monolog/src/Monolog/DateTimeImmutable.php): Failed to open stream: No such file or directory

the file src/Monolog/DateTimeImmutable.php definitely exists in Monolog 2.x: https://github.com/Seldaek/monolog/blob/2.x/src/Monolog/DateTimeImmutable.php

So make sure you are not deleting files from your vendor folder.

sorry @stof , my bad... indeed the file exists, something else going on.. I'll close the ticket. Thanks for the quick reply.
