setup:upgrade Schema creation/updates error in DefinitionAggregator.php

[sanjeevthed6f0]

Hello!

I am trying to setup:upgrade but its giving me this error

Undefined index: version in /var/www/html/vendor/magento/framework/Setup/Declaration/Schema/Db/DefinitionAggregator.php on line 91

I am not able to trace it. How do I fix this?

Hi @sanjeevthed6f0,

Did you installed recently some new module in your store. If yes, then you need to check the installer scripts of your module in Setup Folder. 

If possible, please share with us the code of module setup scripts.

Hope this helps you!

It was a MySQL error. 

SHOW variables LIKE 'version' was returning blank output. I had to re-install MySQL server and problem solved.

Thank you!
