Cannot read property 'values' of undefined"

Hi Ben,

New error popped - never saw it before:

ERRO[0003] handleSummary() failed with error "TypeError: ejs:301
    299|             <h4>Virtual Users</h4>
    300|             <i class="fas fa-user icon"></i>
 >> 301|             <div class="row"><div>Min</div><div><%= data.metrics.vus.values.min %></div></div>
    302|             <div class="row"><div>Max</div><div><%= data.metrics.vus.values.max %></div></div>
    303|           </div>
    304|         </div>

Cannot read property 'values' of undefined", falling back to the default summary  source=console

I don't have a clue why ... because other test suites with setup and teardown functions - the htmlSummary working great.

Maybe something with the options ? but the same options works in other tests:

export const globalOptions = {
  setupTimeout: "5m",
  scenarios: {
    default: {
      executor: "per-vu-iterations",
      vus: 1,
      iterations: 1,
      maxDuration: "1h",
    },
  },
  thresholds: {
    "http_req_duration{scenario:default}": [`max>=0`],
    "http_req_sending{scenario:default}": [`max>=0`],
    "http_req_waiting{scenario:default}": [`max>=0`],
    "http_req_receiving{scenario:default}": [`max>=0`],
  },
  summaryTrendStats: ["min", "avg", "max", "p(90)", "p(95)"],
};

Hi!

I was having the same error, and fixed it by adding a sleep(1); after each check.
My guess is that there is a race condition if you dont sleep, but im not sure.

I hope this helps you :)

Hi, I had already a sleep of 0.1, but changing to sleep(1) worked for some reason...
guess it's something that can be fixed in the source code.

Should be fixed in latest build on the main branch
