Requesting multiple metrics sometimes give different results to requesting them individually

[james-panayis]

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

Checking the responses from the server they are identical, so the bug is in the Python API.

The raw response from the first query includes:

{'value': 29.584584259066062, 'time': 1731.6583251953125}

and:

{'value': 19.169060055914873, 'time': 1731.6583251953125}

and the raw response from the second query includes:

{'value': 19.169060055914873, 'time': 1731.6583251953125}

Not sure why the Python API gets the abort status when a user asks for metrics?
