Today 4 January, is no more possibile to compile/publish the app with the qr code feature. It fails with the following error: Error: Unable to resolve module react-native-camera from /home/gradle/builds/AdaloApp/node\_modules/qr-code-scanner/src/components/QrCodeScanner/index.js: react-native-camera could not be found within the project or in these directories: node\_modules The problem appears also with a new app. Yesterday worked fine without problem. The problems appear today. Thanks in advance ---

Hi Mike, Welcome to the community 🥳 Same problem. > [@My Andriod Build Gets Stuck with an error log](https://forum.adalo.com/t/my-andriod-build-gets-stuck-with-an-error-log/21599/2): > > @suraj I had the same issue last night. It is the QR Code Scanner causing the problem, this will need investigated as the QR Scanner is not an Adalo built component. Once I removed QR Component from the app, all built in the end. @ben1 @anon78309838 I submitted a ticket on this last night. ---

Yes, unfornately, for me, the qr is indispensable. Do you know if exist an alternative? For me is enought to activate the camera. ---

That’s sad. Give me a few minutes and I will fix it up and post it on the PF marketplace ---

yup. stopped yesterday. Guy removed the package from github and the component builder did not version lock the component ![image](https://us1.discourse-cdn.com/flex020/uploads/adalo/original/2X/1/1a9b9eeb983d488dbe723564ec73a8e274e89819.png) ---

Manay thanks for your feedback. How can we solve? Is there an alternative? For me is enought to activate the camera and display video in a square ---

I am testing it now to make sure it builds, but it should work. Go to: [Adalo Components — PragmaFlow](https://adalo.pragmaflowservers.com/install-component) The very last item is QR Scanner, install that. It will show up in your Private section of your components. Replace the QR scanner that you currently have, and uninstall if from the Adalo Marketplace, and use the one from PF. If you do not know how use the PF marketplace, see this [![](https://us1.discourse-cdn.com/flex020/uploads/adalo/original/3X/4/5/453aaaaa4456624034729fbb62c818c6ebe0ea8c.jpeg "PragmaFlow Adalo Marketplace") ](https://www.youtube.com/watch?v=eshUnhfGfYE) ---
