Dit mag in de migratie zelf gefixt worden.

@BobPuts je kunt dit proberen:

sudo su - postgres
psql dsmrreader

update dsmr_consumption_energysupplierprice set description = '' where description IS NULL;

En daarna nogmaals proberen de migraties uit te voeren.

[dennissiemensma]

Er komt trouwens zo ook een fix release aan die het automatisch moet fixen.

[BobPuts]

Opgelost thanks!

Tevens uitgebracht in v4.4.2. Bedankt voor het melden.
