Issue/Introduction
Resolving error "URLDecoder: Illegal hex characters in escape (%) pattern" we get in Invoke REST API activity.
Environment
ALL
Resolution
Char % is used as an escape char with HEX representation of char to encode special characters in URL. So when char % is used in URL or Form Data, it needs to be encoded with %25 to resolve the above mentioned error. For example, if the url is 'http://localhost:1234/testurl/v1/api/user/adhorwb%zsHasj' having % char than we need to replace % char with %25 which transforms the url to 'http://localhost:1234/testurl/v1/api/user/adhorwb%25zsHasj'.
The reason for encoding the form data for char % is that the default content-type is 'application/x-www-form-urlencoded' when form data is used. So the special characters also needed to be encoded. Alternate to encode the % char in form data to resolve the issue, the form data can be send using Multipart.
