What do the chars %7D mean in an url query?

Question

If I access my webapp with the url

/vi/5907399890173952.html

then it works but when I look in the log files then googlebot is trying to access a similar url which generates an exception:

/vi/5907399890173952.html%7D%7D

what does it mean and how can it be handled as an exception? The message from python is:

 /vi/5251302833520640.html%7D%7D 404 20ms 0kb Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) module=default version=release140319

get() takes exactly 3 arguments (2 given)

The regex that I use for the url is

('/vi/(\d+)(\.html?)?', NewHandler)

%7D is the ASCII code for the } character, which is probably leaking through from a template...

You need to use ` instead of " or '.

For example:

`http://localhost:8080/api/v1/user-profile/${userProfileID}/image/upload`

and not:

"http://localhost:8080/api/v1/user-profile/${userProfileID}/image/upload"
