Requesting multiple metrics sometimes give different results to requesting them individually

Description of Bug

Sometimes, when a single metric is requested with get_metric_values, it returns a value for a particular time. But if both that metric and another are requested simultaneously, even if they both have a value at the same time, the value returned for the first metric is None.

Steps To Reproduce

Run this, noting that the run is on trial3. then comment out line 7, uncomment line 8, and run it again:

import simvue

run_id = "AZPKJLrtwr3ZerLi4QNnu8"

client = simvue.Client()

metric_names = ["soot_visibility.z.7_0.avg", "soot_visibility.z.37_0.avg"]
#metric_names = ["soot_visibility.z.7_0.avg"]

all_metric_values = client.get_metric_values(metric_names, 'time', run_ids=[run_id])

for (metric_name, single_metric_values) in all_metric_values.items():
    print(f"{metric_name}: {list(single_metric_values.items())[-1]}")

Output:

soot_visibility.z.37_0.avg: ((1731.6583251953125, 'AZPKJLrtwr3ZerLi4QNnu8'), 29.584584259066062)
soot_visibility.z.7_0.avg: ((1731.6583251953125, 'AZPKJLrtwr3ZerLi4QNnu8'), None)

Output with line 8 instead of 7:

soot_visibility.z.7_0.avg: ((1731.6583251953125, 'AZPKJLrtwr3ZerLi4QNnu8'), 19.169060055914873)

Setup

• OS: Ubuntu
• python-api version v2.3.5

Beginne mit dem Aufruf get_metric_values und führe die bereitgestellte Reproduktion gegen trial3 mit beiden metric_names-Konfigurationen aus. Vergleiche die zurückgegebenen Werte für den gemeinsamen Zeitstempel; abgeschlossen ist die Aufgabe, wenn die Anforderung mehrerer Metriken denselben Wert beibehält, der zurückgegeben wird, wenn die betroffene Metrik einzeln angefordert wird.
