This attraction ran for a very brief period of time. It was advertised in the Disney Planning Video for 1998.

Here is another article which includes some information about the history of the attraction as well.
Must not have been too much of a hit... it was very short lived. Here's what Laughing Place says:
The combination of the show and walkthrough really helped establish a
Goosebumps presence in the Streets of America and brought some much needed attention to this back area of the park. Unfortunately, the timing of the Goosebumps Horrorland Fright Show and Funhouse was just off, happening a little too late. By the time it joined Disney-MGM Studios, the original book series was coming to an end, as was its television show adaptation, and with Stine was working on a new
Goosebumps series, the original
Goosebumps was in a transitional period, so it was difficult to capitalize on the success that the series had in the mid 90s. So with that, the show and walkthrough lasted one more Halloween period before officially coming to an end on November 1, 1998.
