How to Resolve Manually
A default root object is an optional piece of configuration for a CloudFront Distribution. It is an object which is returned to the viewer when they request the root URL (/) instead of a specific object.
Within your CloudFront Distribution, under settings near the bottom of the configuration pieces, you will see this small text box where you can set a default root object. Enter only the object name, for example, index.html. Do not add a / before the object name.
Note: If the file name of the default root object is too long or contains an invalid character, CloudFront returns the error HTTP 400 Bad Request - InvalidDefaultRootObject. In addition, CloudFront caches the code for 10 seconds (by default) and writes the results to the access logs.
