pt-online-schema-change fatal error: undeclared value

After the latest update pt-online-schema-change (version 3.0.8) isn’t working anymore. Seems like a common error which is easy to fix, however for us it means we can’t do any changes for the time being.

Message: Can’t use an undefined value as an ARRAY reference at /usr/bin/pt-online-schema-change line 7514.

Hello thanks for your post.
Can I just check the installation details with you please? OS, MySQL version - anything that will help the engineers identify the specific issue?


Could you specify your MySQL version, if you are using slaves and the command line parameters you used?
