Magento 2.2.7

Getting this error in the error_log and customer get's white screen when trying to login to site,

Fatal error: Uncaught Error: Call to a member function getValue() on null in

Any help would be appreciated. Not sure where this is coming from, all of the products have a weight set.

  • do you have custom module that extends the module-bundle?

This ended up being an old migrated row in the quote table from the M1 to M2 migration. Deleting that row removed the error for the specific customer account.

  • how did you get to know which row is older in the quote table? Oct 27 '20 at 10:44
