Could you please share the link for build failure log?

From Jobs in run #20220719.5 (https://dev.azure.com/mssonic/build/_build/results?buildId=124124&view=results),
I could see sonic-utilites is still with 9f496a0.

Could you please clarify if you did try advancing the sonic-utilities to a6404b7 in your local view and saw the build failure? If so, please share the build log.
