Auto-Update Exchange Rates

How would you implement an auto-update here?

Video of the error when trying it with integromat:

I can see you have a date filed with the Integromat “now” value. That’s a UNIX-style time in seconds since the “epoch” (1st Jan 1970).

Knack only works with formatted dates - see Working with Fields and scroll down to dates. You’ll have to use the Integromat “formatDate” function (See Date & Time Functions Help Docs | Integromat Help Center)
