Content Translation Module Error

Does this site use memcache? If so, it could be #3164651: Errors for content translation module →

I agree that we need to know how to reproduce this before we can work on resolving it.

While this was reported on 10.1, any fix will be applied to 11.x (main) first.

I occasionally encounter this error on multilingual websites as well. It typically resolves with a cache clear via `drush cr` or by running `drush ev "drupal_flush_all_caches();"`.

I have a website with domain module and ~5 translations on the site.

I can reproduce this exception when I make an sql backup with drush (with a bash alias, like: cd ~/website/; vendor/bin/drush cr; vendor/bin/drush sql-dump --gzip >filename.gz).

Then, I get this error in the php error log when I try to access a translated node on the site.

To fix it, I have to clear the cache, then the site and the node above are accessible again.
