I am using the same code that defined in this link to create and send data to modal. But in my-modal-resource.js file, I have the following error.

Cannot read property ‘customKey’ of undefined

Why this issue occurs? Kindly share your thoughts.

Thanks in advance…

I found answer to this question. need to get customKey using context.extension.modal.customKey . It’s need to be changed in https://developer.atlassian.com/platform/forge/runtime-reference/custom-ui-bridge/

Can i use resolvers for the new app that i created to show modal? If yes how can i define resolver function to that modal app?
