We are observing failures to issue token on Chrome clients with the following error message (we only have access to error strings from JavaScript error logs and not the details from PST tab under issuance call details in network tab):

OperationError: Error executing Trust Tokens operation

Based on above, we have the following queries:

1. What are the scenarios in which the above error messages gets triggered? We have seen these errors in scenarios where server returns invalid token in response, or issuer key commitment is not registered but it would be helpful to have an exhaustive list of scenarios where this error can be thrown.
2. Can there be scenarios where key commitment distribution across clients doesn't happen successfully? Are there any metrics/numbers that your team tracks for successful update of key commitments across supported Chrome clients ?
3. Is there a way we can get more details from the exception thrown in case of such Operation errors? The exception string logs the above message which seems very generic in nature in terms of root causing the issue (Is there a way to capture error message shown under network tab which is slightly more descriptive?)

Note: We have successfully registered PST public keys through this Google Chrome repository and haven't rotated them since registration.
