Change Details

This is followup of {T119752} in which the sql script executed was from an older patchset and made the added columns not-nullable. Please correct it by making it nullable as follows ``` ALTER TABLE /*_*/cx_translations MODIFY translation_source_revision_id INT UNSIGNED NULL, MODIFY translation_target_revision_id INT UNSIGNED NULL; ``` There is no gerrit patch related to this since the patchset https://gerrit.wikimedia.org/r/#/c/255662 has correct script.
