Storyline 360 does not recognize index_scorm.html file

Hi Heroes,

I'm trying to create a web object from an html project that was generated by Adobe Captivate and the index file is named index_scorm.html. If I rename it to index.html I get an LMS API error when it launches, which states "content may not play properly and results may not be recorded." 

How can I get SL360 to recognize the web object?

Thanks!
