Failed to fetch data through the API

When doing some API tests I have been hitting this issue:
At some point I did hit that URL:
- https://api.clearlydefined.io/definitions?type=npm&provider=npmjs&continuationToken=bnBtL25wbWpzL0B6eGluZy9saWJyYXJ5LzAuNi4wLWJldGEuMQ==
- the `continuationToken` in that JSON was `"continuationToken":"bnBtL25wbWpzL0B+bGlzZmFuL2xvZ2dlci8xLjEuMC1iZXRhLjA="` (e.g. `npm/npmjs/@~lisfan/logger/1.1.0-beta.0` when base64-decoded)
(See attached payload [definitions.json.txt](https://github.com/clearlydefined/service/files/3888915/definitions.json.txt) )
- Following the continuation token and getting https://api.clearlydefined.io/definitions?type=npm&provider=npmjs&continuationToken=bnBtL25wbWpzL0B+bGlzZmFuL2xvZ2dlci8xLjEuMC1iZXRhLjA= yield exactly nothing at all... an empty page ( HTTP Status code: 200 OK )

The only odd thing in that seems to be the `@~lisfan` scope with tilde? Other than that it could be some CloudFlare thing?
