Downgrade SharedStorage out of budget log level messages

[ankwok]

Hello,

As an ad tech with Javascript tags on client websites, we do our best to catch any errors and properly treat them as to not negatively impact the client's website behavior. Clients routinely monitor the console activity on their websites and complain to us when our JS tag produces error messages in the console.

The Shared Storage API has a budgeting mechanism with clearly defined behaviors when we try to perform an operation like selectURL when no budget remains. However, Chrome logs an error when this expected behavior happens. Our JS code cannot catch it since no error is thrown. This is by design otherwise an actor would be able to know whether or not they have any remaining privacy budget.

We would like Chrome to downgrade such logging to warning or info as it is:

1. Expected behavior
2. Not very actionable as the caller cannot observe these console logs

Hi, @ankwok, downgrading the severity of this console error sounds reasonable to me.

Could I trouble you to file this as a new issue on the Shared Storage repo? https://github.com/WICG/shared-storage

Thanks!
