I have recently noticed my phone getting quite warm whilst browsing using Safari. I connected my phone to my Macbook Pro and retrieved the logs. There are a LOT of the following while Safari is open (190,000 lines in a 42 second capture):

error    18:46:59.808300-0400    MobileSafari    WebContent[706] Promise rejected: Invalid call to runtime.sendNativeMessage(). The operation couldn’t be completed. (SFErrorDomain error 3.).
error    18:46:59.808315-0400    MobileSafari    WebContent[706] Promise rejected: Invalid call to runtime.sendNativeMessage(). The operation couldn’t be completed. (SFErrorDomain error 3.).
error    18:46:59.808329-0400    MobileSafari    WebContent[706] Promise rejected: Invalid call to runtime.sendNativeMessage(). The operation couldn’t be completed. (SFErrorDomain error 3.).
error    18:46:59.808341-0400    MobileSafari    WebContent[706] Promise rejected: Invalid call to runtime.sendNativeMessage(). The operation couldn’t be completed. (SFErrorDomain error 3.).

I uninstalled 1Password from my phone and this error message went away entirely. I then re-installed it and it came back. Then I disabled the Safari Extension and it went away.

I am not in lockdown mode. I have logs I can send directly to support should need be.

I’d love to fix this! For now I can keep the extension disabled, but that doesn’t seem like a great long term solution.

Thank you,

Jonathan
