Hey, I have a multistep paywall it’s works fine but in moment I add “Single Choice” component button on the second step it’s just stop working

- If I try to preview it in RC app then just continue button on step 1 do nothing (it worked just before I added single choice)
- If I open it inside my flutter(ios) app I see the error instead of paywall (Backend Error 8) and following logs:

Error: Swift.DecodingError.dataCorrupted(Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "screens", intValue: nil), _CodingKey(stringValue: "pw41e8848e277347b6", intValue: nil), CodingKeys(stringValue: "componentsConfig", intValue: nil), CodingKeys(stringValue: "base", intValue: nil), CodingKeys(stringValue: "stack", intValue: nil), CodingKeys(stringValue: "components", intValue: nil), _CodingKey(stringValue: "Index 2", intValue: 2)], debugDescription: "Failed to decode unknown type \"input_single_choice\" without a fallback.", underlyingError: nil))


 



Rc app is up to date from appstore and flutter sdk version is 10.13.2

    Hey there,

    Thank you for the message. Matt from RevenueCat here!

    This is an interesting one, and one I want to take a deeper dive into to fully understand what is happening here. Could you private message me which of your projects this is for, along with the name of the paywall, please?

    I can see some similar paywalls on your account, but I want to make sure we’re looking in the right place so we can get this resolved as quickly as possible for you!

    Thanks!

      Hey ​@ivan-kolchev-51cdfa,

       

      Thank you for the information in the private message. That really helped us understand what happened here.

       

      Unfortunately, “Single Choice” and “Multiple Choice” components are not currently supported in multi-page paywalls. These components are from Funnels, which is a separate feature from Paywalls.

       

      We investigated how this happened, and found that this was caused by a bug in the AI bot within the paywall editor. The team are already working on a fix with high priority, and this will be deployed as soon as possible to prevent these components from being incorrectly created within a paywall.

       

      This component allowed the paywall to enter a broken state, which led to the issues we discussed in the private messages.

       

      I’m sorry for any confusion this caused. The team are working to ensure this doesn’t happen again, as well as adding extra validation to make sure issues like this are caught within the editor and provide additional safety here.

       

      As this component is not currently available within paywalls, the recommendation for now is unfortunately to delete these choice components from your paywall and work with the “Continue Button” instead. I’m sorry, as I understand this is disappointing news.

       

      If I can assist with removing these components, or if you have any additional questions, please let me know. I’ll be delighted to do everything I can to help.

       

      Thanks,

      Got it, yes, it came from AI editor when I tried edit the paywall

      We already found the workaround to use instead of the single-choice but it would be nice to have those components in future for paywalls also!

      Hey ​@ivan-kolchev-51cdfa,

       

      Thank you for confirming this came from the AI editor. The team are close to deploying a patch to stop this from happening again.

       

      I have also raised your request for this functionality to be added to paywalls!

       

      I’m sorry again for the confusion here! If there is anything else I can do to help, please just let me know!

       

      Thanks!
