Import failed, Settings: plans is not iterable

I try to migrate my ghost installation.
The version on the source server is 3.36.0 (the latest one). The version on the target server is the same.
I export the content on the source server to a json file, delete all content on the target server and then I try to import the json file. I always get this error:

Import failed

Settings: plans is not iterable

{“key”:“stripe_plans”,“value”:"",“type”:“array”,“created_at”:“2020-07-01T15:50:35.000Z”,“updated_at”:“2020-07-01T16:12:28.000Z”,“group”:“members”,“flags”:null}
Is there a quick workaround (changes in the source db and re-export or changes in the json file)?
Kind regards,
Jacques Bopp

Try changing the value to "[]" (currently "")

Thanks. Works.
