TypeError: Converting circular structure to JSON - Uploading Contract

• What is the current behavior and expected behavior?

I want to upload an ink! Smart contract using the PolkadotJS UI portal in a local node that runs with the pallet contracts on it. To replicate this issue the Substrate Contracts Node can be used.

When I click the button Upload & deploy code and upload the files the screen keeps loading, and in the Developer Console the following error appears:

TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'r'
    |     property '_events' -> object with constructor 's'
    |     property 'ready' -> object with constructor 'i'
    --- property 'context' closes the circle
    at JSON.stringify (<anonymous>)

I can upload the contract using other alternatives using Contracts UI and using the tool cargo-contract.

The issue is still persisting. Something crucial like this shouldn't be unfixed for 2months+.

If its that crucial, I would suggest you help out and open a PR then.
