How to store a small list in scientificMetadata?

[jkotan]

Currently we are testing scicat backend 4.16.0 . Unfortunately, in this version possibility of storing a small list like [1, 0 , 0] was removed. Instead I get the following errors

More than two values provided in the quantity_range field {"inputValue":[1,0,0]}

Is there any possibility to store small lists?
Of course it is only possible way I can dump it to {"1":{"value":1}, "2":{"value":0}, "3":{"value":0} } but it will use more storage space in DB.
It looks like #924 was not resolved .

The dataset in DB is OK but the error message is misleading
