Yes, it is incorrect. The intended meaning here is "a short period of time", not "for or during a short period of time", and thus the correct one to use is the noun phrase "a while", not the adverb "awhile".

Eg "I waited awhile"

but:

"It took me a while to get there".

Lots of people (professional authors included!) get this wrong.
