Hi - I don't think any changes were made in Qlik Web Connectors.
Is this for QlikView or Qlik Sense and is it possible you also changed the version of that?
Could you also let us know what table(s) you are using and whether it is a particular input parameter which is making up most of these characters?
We are using the General Web Connector, JsontoTable, using the "Get" method. The Request URI * gives a pop up error message if the url is greater than 1000 characters after version 2.0.1. We have a very long Workday url that is greater than 1000 characters and were unable to move forward with any version after that. See error message below. Note, exact same URL and method work on version 2.0.1 but not after that.
I've been able to "install" version 2.0.1 on new servers by copying a version I had on a different server over to the new server.
