Hi.
Open the Terminal window with a right click on the mouse. Then, select open as admin or something similar.

Hi.
I’m sorry, but I didn’t understand your question.
Are you having issues with our tutorial, or is it with your modified version only?

In reply to Bruce. Looks like the path info was filtered out. It should be Userid/deviceID/date/data. The dataStringPath would be similar: const dataStringPath = 'Userid/deviceID/date';

Hi and thanks for the great tutorial on Firebase. I am trying to adapt your instructions to use on my own project but I’m not seeing any data/records being displayed on the web page. Can you recommend a way to troubleshoot this? It’s probably a path issue but I’ve tried several changes and deployed them but still nothing and I’m not sure how to debug this.

My path looks similar to ///. The path, as defined in app.js is //

Can you recommend some troubleshooting tips as to how to debug this?

Thanks.

Hi.
You’re probably wrong credentials or wrong database URL.

Hello, thanks for the tutorial. You guys are doing a lot of nice work,
Please I’d like to show your the error message that is displaying on my serial monitor. I tried so much to debug the error but still doesn’t work.
Here’s the error message:

Token info: type = id token (GITKit token), status = on request
Token info: type = id token (GITKit token), status = error
Token error: code: -4, message: connection lost

Hello!
I was using this guide for my project in November 2022, and my hosted page works and my project too.
But now i need to use this project again and when i try to use it , it doesn’t work.
The console log of my firebase web app says:
/__/firebase/9.9.1/firebase-performance-compat.js net::ERR_BLOCKED_BY_CLIENT

app.js:137 The read failed: Error
util.ts:491 Uncaught (in promise) Error: permission_denied at /owners: Client doesn’t have permission to access the desired data.

Don’t change anything and it should work like it did in October. Maybe it’s something because I’m using old versions of firebase?
(I already changed the database rules to have access)
Thanks!
