Unable to claim 1Password Github Student Developer pack offer

Hi, when trying to claim 1Password Offer through the Github Student Developer pack I keep running into an error which says "something went wrong" Can someone guide me on how to fix this and claim my offer. Thank you!

P.S- I've attached a screenshot of the error received and I tried to claim it in many different browsers such as Firefox, safari and chrome but the error persists. 

Please guide on how to claim the offer and fix the error.
