I’m creating an app for my university project. My app is functioning as I’d like it to on the web preview but not on the mobile testing app.
The user can upload a photo or file from their device and view it using the web viewer, again this works fine on the web preview tester. However in the app I’m getting a NSPOSIXErrorDomain and a NSURLErrorDomain error.
I should add that it works once, so the first photo or file is viewable in the web viewer. If the a second photo or file is selected from the list then I get the error.
I have tried a few things to remedy this, I’ve updated the testing app, I’ve updated my phone, I have tried using a different database type (I’m currently using a local database) but this broke functionality.
I’ve tried to research this error and it seems to be related to permissions and access? But I’m stuck on how to remedy this and if it’s a me problem or a thinkable problem.
Hopefully someone can help, I’ve included two screenshots of the errors.
Thanks,
Hattie 
A quick update, I have re created the blocks used in this section of the app and I no longer get the error code. However my web viewer does not update from the first opened file.
For example, lets say I save two files ‘File A’ and ‘File B’. If I open File B, the web viewer will show File B. This works as intented. If I then selected File A, the web viewer still only shows File B.
This only happens of the Thunklable Live Testing App. The Web Live Tester works perfectly, this is why I am getting a bit frustrated.
I am trying to figure out of its a problem I have caused (issues with the code, etc) or if its on Thunkables end. I am leaning to it being a Thunkable App issue and as it works on the Web Tester.
Hello @hattie.nunwickj758n9
Could you please share a screenshot of your blocks?
Here is my blocks for viewing the file/photo in the web viewer and for uploading a file/photo to the database.
I have made a work around using a pdf viewer for pdf files, and usong and image component to view photos. This works, so at the moment my app functions as I want it to. However the web viewer is still getting this error.
Thank you for helping.
