Triage Service exceptions: Request path contains unescaped characters (/definitions)

TypeError [ERR_UNESCAPED_CHARACTERS]: Request path contains unescaped characters

requests 
| where resultCode == 500
| join (
 exceptions
 ) on operation_Id 
| extend pathPrefix = extract("/(\\w+)", 0, tostring(operation_Name))
| where outerMessage contains "ERR_UNESCAPED_CHARACTERS"

This is the definitions search endpoint:
https://github.com/clearlydefined/service/blob/master/routes/definitions.js#L29
Looks like 'request' is throwing before actually trying to make a call. I think this is a clear case of missing input validation in the service. Should be a bug, not a silence
