Google Sheets API batch update updateChartSpec does not update right axis viewWindowMax - google-sheets-api

Question

What I really want is a combo chart where right axis and left axis have the same viewWindowMax which is the one that will let all the data in the chart.
For this, I try to get the highest of the 2 and set both of them to that max.
batchUpdate of a chart in google sheets requires to update the whole chart["spec"] with updateChartSpec. I have test cases where I set viewWindowMax to a hardcoded arbitrary number. It updates properly the left axis, but the left axis goes back to a default condition with an empty viewWindowOptions even if it did have some other value before the update. IE I get this result with no error message:
{'position': 'LEFT_AXIS', 'viewWindowOptions': {'viewWindowMin': 0, 'viewWindowMax': 40, 'viewWindowMode': 'PRETTY'}}, {'position': 'RIGHT_AXIS', 'viewWindowOptions': {}}
when in the request it was like so:
{'position': 'LEFT_AXIS', 'viewWindowOptions': {'viewWindowMin': 0, 'viewWindowMax': 40, 'viewWindowMode': 'PRETTY'}}, {'position': 'RIGHT_AXIS', 'viewWindowOptions': {'viewWindowMin': 0, 'viewWindowMax': 40}}
removing the 'PRETTY' thing or adding it changes nothing.
Full request code looks like this:
requests = [
{
"updateChartSpec": {
"chartId": chart['chartId'],
"spec": spec
}
}
]
body = {
'requests': requests
}
response = build('sheets', 'v4', credentials=creds.credentials).spreadsheets().batchUpdate(
spreadsheetId=spreadsheet_id, body=body).execute()
with spec variable =
