Circular error with MongoDB Stitch authenticated user

Hello all,

I’m using https://www.npmjs.com/package/mongodb-stitch-server-sdk with Typescript and I get circular error when I try to set user object to a state: client.auth.user

create.js:7 Uncaught TypeError: Converting circular structure to JSON --> starting at object with constructor 'StitchUserImpl' | property 'auth' -> object with constructor 'StitchAuthImpl' --- property 'currentUser' closes the circle at JSON.stringify (<anonymous>) at createKey (create.js:7) at Object.get key [as key] (create.js:19) at StoreRegistry.generateKey (registry.js:49) at registry.js:35 at useSweetState (hook.js:79) at LoginForm (LoginForm.tsx:16) at renderWithHooks (react-dom.development.js:14825) at mountIndeterminateComponent (react-dom.development.js:17505) at beginWork (react-dom.development.js:18629) at HTMLUnknownElement.callCallback (react-dom.development.js:188) at Object.invokeGuardedCallbackDev (react-dom.development.js:237) at invokeGuardedCallback (react-dom.development.js:292) at beginWork$1 (react-dom.development.js:23234) at performUnitOfWork (react-dom.development.js:22185) at workLoopSync (react-dom.development.js:22161) at performSyncWorkOnRoot (react-dom.development.js:21787) at scheduleUpdateOnFiber (react-dom.development.js:21219) at updateContainer (react-dom.development.js:24407) at react-dom.development.js:24792 at unbatchedUpdates (react-dom.development.js:21934) at legacyRenderSubtreeIntoContainer (react-dom.development.js:24791) at Object.hydrate (react-dom.development.js:24857) at renderReactElement (index.js:38) at doRender$ (index.js:44) at tryCatch (runtime.js:45) at Generator.invoke [as _invoke] (runtime.js:271) at Generator.prototype.<computed> [as next] (runtime.js:97) at tryCatch (runtime.js:45) at invoke (runtime.js:135) at runtime.js:170 at new Promise (<anonymous>) at callInvokeWithMethodAndArg (runtime.js:169) at AsyncIterator.enqueue [as _invoke] (runtime.js:192) at AsyncIterator.prototype.<computed> [as next] (runtime.js:97) at Object.push../node_modules/next/node_modules/regenerator-runtime/runtime.js.exports.async (runtime.js:216) at doRender (index.js:40) at render$ (index.js:25) at tryCatch (runtime.js:45) at Generator.invoke [as _invoke] (runtime.js:271) at Generator.prototype.<computed> [as next] (runtime.js:97) at tryCatch (runtime.js:45) at invoke (runtime.js:135) at runtime.js:170 at new Promise (<anonymous>) at callInvokeWithMethodAndArg (runtime.js:169) at AsyncIterator.enqueue [as _invoke] (runtime.js:192) at AsyncIterator.prototype.<computed> [as next] (runtime.js:97) at Object.push../node_modules/next/node_modules/regenerator-runtime/runtime.js.exports.async (runtime.js:216) at render (index.js:25)

Closing for now as a workaround is possible. If someone else in future will report problem with JSON.stringify then will harden the logic around it
