Pattern

Webview-Based OAuth Breakage

inapp-webview-onboarding-redirect-breakage

A recurring scenario where embedding hosted onboarding (e.g., Stripe flows) inside an in-app webview prevents required navigation or redirect steps, leading to stalled or blank screens, so the only reliable workaround is opening universal/native Safari.

Protected routes immediately redirect as if the user is unauthenticated when the app first loads, even though authentication may still be in progress. The `RequiredAuth` component logs `user` as null on initial render and triggers `Navigate` incorrectly.

In iOS Safari, opening the ShadCN Drawer and focusing an input causes the drawer height to shrink and not behave correctly when the keyboard opens.

When using React-Joyride with the shadcn Sheet (Radix UI), the tour skips ahead and cannot continue because clicking outside the sheet closes it, unmounting the JoyRide component.

the Vercel app immediately bounces me back to my log-in screen — deploying with Vercel. Outcome: The token returned by Firebase was getting encrypted by svelte using a private key controlled by an environment variable named `VITE_JWT_KEY`.

I was facing the same error during build — That's my home page. Where I am using FeaturedVacancies. Tension: reason being I was getting the cookies in fetchwrapper for auth token. Outcome: solved my issue.

I get exception of Invalid saml response. — I redirect the browser then from XYZ app to Keycloak using the redirect URI i get from Identity provider i configured. Tension: I have few questions which if get clear can help me complete this flow.

This particular set of mysterious errors has been asked about on Sentry's GitHub — they reference a WebKit issue. Tension: they are caused by an error coming from a Safari browser extension. Outcome: can safely be ignored, or filtered.

Safari DevTools console shows full details, but JS code only gets "TypeError: Load failed"

RedirectResponse goes to "/" without the authentication cookie

When I send an HTTPS request using the Swagger UI. Tension: the redirection then fails. Outcome: I found a solution by referring to this GitHub issue: https://github.com/encode/uvicorn/issues/369.

Stripe payment flow between a FastAPI backend (creating PaymentIntents) and a Vue frontend (confirming using the PaymentIntent ID) is causing issues during the payment process on the frontend.

Stripe never renders (just a white screen) — WKWebView. Tension: it appears Stripe’s onboarding is blocked in WKWebView. Outcome: SFSafariViewController delegates don’t expose intermediate redirects.

Stripe.PaymentSheet is NOT supported for web. — accepting card payments in my Flutter web app. Tension: I am just unable to fill the missing blocks.

Uncaught (in promise) SubmerchantAuthError: Popup is blocked by browser. — once i click it. Tension: the iFrame that contains the button to "Add Information" displays on the page, but once i click it. Outcome: Even so, a popup does open but shows just a loading indicator.

POST https://api.hcaptcha.com/authenticate 401 (Unauthorized) — this is only happening on the web not on the native apps. Tension: {"pass":false,"error-codes":["pat-missing-auth"]}. Outcome: the hcaptcha 401 issue disappeared.

settings these breaks Stripe. It blocks the request — I've used it for many projects and the Stripe integration works flawlessly. However for a new project I needed to incorporate ffmpeg. Tension: I've literally tired every possible permutation of headers with different values but in all cases either Stripe works but ffmepg doesn't. Outcome: The customer portal works but checkout doesn't.

.NET MAUI has no explicit Stripe Tap to Pay integration guidance

the redirect would be blocked by browser after successful payment — if I load the addin in a office web (microsoft 365) excel document in the browser. Tension: it is actually trying to navigate the top level window. Outcome: How can i achieve the behavior that the taskpane addin that is hosted inside should only be redirected?

Mobile browser: Safari (iPhone). Tension: On desktop Safari, everything works fine. But on mobile Safari, there's no spacing between elements. Outcome: The lack of CSS nesting can be a significant influencing factor.

Signing in with the NextAuth VK provider fails with `invalid_request` and `Code challenge method is unsupported` when performing the OAuth code challenge flow in Next.js 14.

Embedding a CPQ web app as an iframe inside Salesforce fails to persist authentication cookies/session for API calls. Login in a new tab isn’t recognized inside the Salesforce iframe, preventing authorized requests.

Allowing users to upload and embed their own web components as dashboard widgets, while preventing them from accessing cookies or other data on the hosting page without manually auditing each widget.

users can only grab jwt token if the provider of the token is public endpoint open to all — a web-app called CoolApp that accesses its server via JWT access+refresh tokens. Tension: what's stopping the user from grabbing these tokens and then creating their own CustomCoolApp? Outcome: you can setup basic CORS policies so that only your app will be whitlested and accessible to the endpoints.

Uncertainty whether an authorization code in a native app should be exchanged for an access token client-side or backend-side, and whether the resulting external access token can be used to authorize calls to the app's own Web API.

When a page is served with Cross-Origin-Opener-Policy: same-origin inside a cross-origin iframe, calling window.open returns null in the parent page console, even though the popup tab opens successfully.

I can pass user id through a query string — When consumer click on the "dashboard" link on Mobile App. Tension: how can I make them sign in to our Web app without going through another Login screen. Outcome: I have read a bit about SSO, is that right direction I am thinking towards?

it is also required to "forget" the token right after exiting/closing the app — I have a web API which uses JWT tokens for accessing resources. Tension: The issue with (1) is that it's not cleared when a browser's tab is closed but only when all the windows are. And (2) is not secure since if an attacker manages to inject a code into a client he will be able to extract the access token.

When calling the OpenAI API directly from an iOS app, the Authorization Bearer API key appears in network traffic and can be captured/decoded with HTTPS sniffing tools. This allows others to extract and reuse the key.

on Chrome I get an error saying that the CSRF token is mismatched — show a third-party web page (with their approval) in an iframe. Tension: This site has a different domain to my parent site. Outcome: The site displays fine on firefox.

When the MUI Select dropdown is used inside an iframe, selecting any option causes the viewport to soft scroll to the top of the form.
