Cannot read property 'List' of undefined

Cannot read property 'List' of undefined



I get the following Error while fetching data in my App. 

"Cannot read property 'List' of undefined"

Can anyone tell me what i do wrong?



Hey Arnold,

can you please provide a bit more context? Is this a mobile app or a web app? Which OutSystems version are you using? Which stack? Which database?


I'm using V10 and building a mobile App

I use a static Entity with a extra numeric Field. 

When  I changed the value of this field , an error will raise in my app on the pages where this entity is used in a aggregate.
