Brightcove integration with AEM

I am installing brightcove connector on AEM 6.3 version in windows environment.Following the instructions provided in https://support.brightcove.com/adobe-aem-brightcove-connector-configuration.

Setup and configuration is successfully done. However bright cove admin page http://localhost:4502/brightcove/admin loading symbol shows up and couple console messages.

Failed to load resource: the server responded with a status of 404 (Not Found)

admin:1 Refused to execute script from 'http://localhost:4502/bin/brightcove/api.js?account_id=undefined&a=search_videos&callback=showAllVideosCallBack&sort=name&limit=30&start=0&fields=id,name,shortDescription,longDescription,publishedDate,lastModifiedDate,linkURL,linkText,tags,thumbnailURL,referenceId,length,economics,videoStillURL' because its MIME type ('') is not executable, and strict MIME type checking is enabled.

Any help much appreciated.
