Cannot read properties of undefined (reading 'isProxied') - json

Question

I want to query the database by id to display the data. I run into this error. "Unhandled Promise rejection: Cannot read properties of undefined (reading 'isProxied')". Perhaps someone has encountered this error. Please tell me how to solve it.
