Error when approving: Illegal characters in options string

[Anonymous]

Anyone know what this error means? Trying to approve an alert email and it's giving me this message:

Thanks Jim Thao​ and Iryna Zhuravel​.

I think the error message is just condensing the actual copy...my actual email looks like this:

That is indeed weird.  Anything funky in the plain-text version of the email?

Aha! You are correct. The text version was parsed. Take the rest of the day off (boss permitting)!

Seems like you are missing closing brackets in the "Role" token, Marketo does not recognize it, hence the error
