Withings integration no longer functional: 'Arrow' object has no attribute 'int_timestamp'

The problem

Up until the last few days, the two Withings integrations that I have configured (for the wife and I) have been fairly stable for pulling Withings/Nokia Sleep data.

Recently, this integration has failed and no longer seems to initialise during startup — the following error is returned

'Arrow' object has no attribute 'int_timestamp'

I believe Withings have/are in the process of moving to a new version of their API; however, I’m not sure if that is what is causing the issue here.

What is version of Home Assistant Core has the issue?

core-2021.5.5

What was the last working version of Home Assistant Core?

core-2021.5.5

What type of installation are you running?
