Clone project failes in v2018.8.5 and v2018.8.8

I am currently unable to clone any projects. Here is the error from the log:

Thanks for getting in touch! I’m sorry to hear you’re hitting this unexpected issue. I suspect you’re hitting a known bug which prevents projects that have scheduled triggers configured on them from being cloned. Does this match your scenario? You can reference the bug report at the following link.

The fix for this issue will be included in the next patch release which should be shipped very soon. The workaround in the meantime is to delete the scheduled trigger on the project you’re trying to clone.

I hope this helps! Let me know if this doesn’t match your scenario and I’ll be more than happy to dig into it more. :slight_smile:

Best regards,
