I have a problem with adding translation to block_content basic block.
My default lang is english and if I create new Content Block -> Basic block in english version everything is ok but later if I try translate this then I get error like bellow.
nvalidArgumentException: Invalid translation language (pl) specified. in Drupal\Core\Entity\ContentEntityBase->addTranslation() (line 989 of /var/www/web/core/lib/Drupal/Core/Entity/ContentEntityBase.php).
It only doesn't work for Content Block. Rest of entities like nodes, paragraphs, media works as expected. I also turn on the option Enable translation.
I noticed that this conditional
<?php
if (!isset($this->languages[$langcode]) || $this->hasTranslation($langcode) || $this->languages[$langcode]->isLocked()) {
throw new \InvalidArgumentException("Invalid translation language ($langcode) specified.");
}
?>in ContentEntityBase::addTranslation , second condition $this->hasTranslation($langcode) is true, but should not be true because there is no translation for this version yet.
