undefined method `fixed_offset_time_zone'

[the-invisible-man]

Hi, I'm having some issues trying to add a payment method to an existing account using the stripe plugin. I thought for a second it might be that my request wasn't formatted correctly but then I tried with the sample on the readme page and I received the same error. I've tried installing the plugin manually and through kpm but still not luck. Any help would be much appreciated 💯

I'm attaching the logs:
