I recently upgraded from 3.x to 4.x. Running database update block_class_update_20017 I got this error:
json_decode(): Argument #1 ($json) must be of type string, array given
In block_class.install, function block_class_update_20017 I found the source of my error in row 445:
$block_classes_stored = Json::decode($block_classes_stored);
This expects $block_classes_stored to be a string, and converts it in array. The error comes because my configuration is already a string. This comes from my block_class.settings.yml:
block_classes_stored:
- col
- col-12
- mt-3
- col-sm-6
- col-md-4
I solved putting the row in a if statement which checks that $block_classes_stored isn't an array already:
if (!is_array($block_classes_stored)) {
$block_classes_stored = Json::decode($block_classes_stored);
}
I hope the logic is correct and that this could help other people.
Attaching patch.

4.0
Code
Seems duplicated in favor of 🐛 Failsafe conversion of block_classes_stored Active , isn't?
Whoops! I looked for issues with the error code and the database update and couldn't find that!
Thanks!
No problems at all. Btw, thanks for reporting and providing the patch
I hope that we can commit soon
