This seems to be happening in cases where the name is not explicitly set on the story so it will likely be fixed by https://bugs.chromium.org/p/chromium/issues/detail?id=720002
when the name is explicitly set in story creation, page_data.get('name') succeeds here: https://cs.chromium.org/chromium/src/testing/scripts/run_telemetry_benchmark_as_googletest.py?sq=package:chromium&q=run_telemetry_benchm&l=93
When the name is not set, it defaults to using the full url in the "failures" output in json output.

json output formatter's code is in https://github.com/catapult-project/catapult/blob/master/telemetry/telemetry/internal/results/json_output_formatter.py

Yep it was fixed by explicitly setting the test name
Example: https://luci-logdog.appspot.com/v/?s=chrome%2Fbb%2Fchromium.perf%2FAndroid_One_Perf%2F170%2F%2B%2Frecipes%2Fsteps%2Fblink_perf.bindings_on_Android%2F0%2Flogs%2Fjson.output%2F0
{
  "failures": [
    "structured-clone-long-string-serialize.html",
    "structured-clone-json-serialize.html",
    "structured-clone-long-string-deserialize.html",
    "structured-clone-json-deserialize.html"
  ],
  "successes": [],
  "valid": true
}
Marking as obsolete
