Uncaught (in promise) Error: Pica: cannot use getImageData on canvas, make sure fingerprinting protection isn't enabled

[rozek]

Hi!

I just tried the example found at https://example-pets.jazz.tools/ and did not even succeed to run it locally - see the following error log from my browser:

Uncaught (in promise) Error: Pica: cannot use getImageData on canvas, make sure fingerprinting protection isn't enabled

Additionally, I also could not open a websocket connection to your server(s) (as described in my previous issue).

Any idea how to proceed?

Hi @rozek, thanks for trying! Which browser/OS are you using?

[rozek]

Hello,

thanks for your response!

I am using macOS Ventura 13.6 with the latest Brave Browser Version 1.66.110 Chromium: 125.0.6422.60 (Offizieller Build) (arm64)

Are you by chance using Brave's "Strict fingerprinting protection mode"?

[rozek]

Similar to the other issue I mentioned above, I tried the example again today - and it worked now.

Could it be that the error I reported was just a consequence of the missing websocket connection?

[aeplay]

I'd be surprised, because the image resizing is a completely local operation and should work/not work the same regardless of if you have a working connection to the sync server.

You didn't by chance update Brave in the meantime? (it sounded like they were working on exactly the fingerprinting strictness)

[rozek]

well, it could be that I updated Brave (as that happens quite often) but I can't tell you for sure.

Anyway, thanks a lot for your effort!
