The problem occurred because of a particular .png image (actually 39 of 
them).  I was able to upload it to blob store and even view it in blob 
store viewer. 

But get_serving_url fails with an null exception when trying to create a 
url.

I am also not able to upload it here with the image icon ... it says it is 
not a valid png.

There is clearly something wrong with it but it is good enough to be able 
to convert.

Pretty confusing.
