the failure is from envoy-filter-example build. somehow bazel 4.0.0, which is ahead 3.4.1 that istio 1.8 is using, and a deprecated bazel rule param causes the failure. In upstream envoy CI, there is a sync flow to handle envoy-filter-example repo git submodule sync. However the sync is very envoy ci specific, so hard to use and maintain at Istio CI. I tried to turn off the example build, but cannot find a working env variable.. I think we can just comment out these two blocks in ci script:

envoy/ci/do_ci.sh

Lines 218 to 223 in 81b7bb3

	if [ "${ENVOY_BUILD_FILTER_EXAMPLE}" == "1" ]; then
	echo "Building and testing envoy-filter-example tests..."
	pushd "${ENVOY_FILTER_EXAMPLE_SRCDIR}"
	bazel_with_collection test "${BAZEL_BUILD_OPTIONS[@]}" "${ENVOY_FILTER_EXAMPLE_TESTS[@]}"
	popd
	fi

and

envoy/ci/do_ci.sh

Lines 242 to 247 in 81b7bb3

	if [ "${ENVOY_BUILD_FILTER_EXAMPLE}" == "1" ]; then
	echo "Building and testing envoy-filter-example tests..."
	pushd "${ENVOY_FILTER_EXAMPLE_SRCDIR}"
	bazel_with_collection test "${BAZEL_BUILD_OPTIONS[@]}" -c dbg --config=clang-tsan "${ENVOY_FILTER_EXAMPLE_TESTS[@]}"
	popd
	fi
