Checkbox Custom Field not showing the value come from API

[Ugur Kadakal]

Hi,

When I get card details from endpoint:

https://api.trello.com/1/board/607eb929ee33c047e810692f/cards?customFieldItems=true

Response is: 

But when i check UI, this field seems unchecked.

I'm using 

https://api.trello.com/1/card/607eb929ee33c047e8106981/customField/61962fddd0a2aa0b899b767b/item

to update; 

Request: 

{"value":{"checked":"true"}}

Response:

{"id":"61962fe1b8484c5db933bdd1","value":{"checked":"true"},"idCustomField":"61962fddd0a2aa0b899b767b","idModel":"607eb929ee33c047e8106981","modelType":"card"}

Am I missing something, or is there any issue about that?

We found the solution, when we send true / false as string, it works.
