The CI failure in pkg/erc4337/preset appears to be unrelated to our changes in the taskengine components. The error is 'paymaster deposit too low' which is not connected to our HTTP error handling improvements. Can we re-run the CI checks?

The CI failure in pkg/erc4337/preset is unrelated to our HTTP error handling changes. The core/taskengine test was canceled only because of this unrelated test failure, not because of any issues with our changes. Could we get a re-run of the CI checks?

The test looks correct but failed due to the below errors

Hi @v9n, I reverted the previous change and updated core/taskengine/vm_runner_rest.go. Please check out my two comments below again.

The s.Success set is solely depending on the err value here now.

These missing fields are updated, and verified in TestContractWriteSimpleReturn that they are set.
