Greetings,
There seems to be some weirdness with the casing of this class, it was renamed to APIRequestCreateCapTIOn in version 22.0.1
I saw a similar issue was brought up (and resolved) last year about the casing for some AdAccount.java internal class names but I am unsure if it is related. Please find the changes from 22.0.0 -> 22.0.1 in the sample screenshot below.
Thank you
