Hi Rhys,
Thanks for taking the time to report this.
Unfortunately, I’ve been able to replicate the same issue on my end. It seems it’s only a validation error.
I have logged a bug report for this so it can be addressed in one of our next maintenance releases of our plugins.
I will set this thread’s status to “Pending Fix” and link it to the report. This way, we will notify you once a fix is released.
The good news is you can workaround that error by modifying the event url to use .com instead of .co.uk and it should import the event as normal.
Please let me know if this works for you.
We apologize for the inconvenience and we appreciate your patience while we work on this.
Thanks,
Victor
