Hi Brian,
client reported creating a landingpage (cp/publish/edit/entry/807) and when they open the entry in the cp they get the following error.
The site was recently updated from EE5.4.0 and bloqs 4.5.1 (i believe)

Return value of BoldMinded\Bloqs\Model\BlockDefinition::getInstructions() must be of the type string, null returned
user/addons/bloqs/Model/BlockDefinition.php:369

Stack Trace: Please include when reporting this error
