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

Inizia con la chiamata a get_metric_values ed esegui la riproduzione fornita su trial3 usando entrambe le configurazioni di metric_names. Confronta i valori restituiti per il timestamp condiviso; il lavoro è completato quando la richiesta di più metriche conserva lo stesso valore restituito quando la metrica interessata viene richiesta singolarmente.
