Hi,

Issue: Connect Http is blanking out " " and passing blank values.
Impact: Service is failing as null values are getting passes.

We upgraded from Pega 5.5 Sp1 to Pega 7.1.8.
In 5.5 " " value was getting appended in URL as +

In 7.1.8 " " value is getting appended as blank

Due to this service is failing as with error-Cannot assign MRM-defined null value. Nulls not allowed for this element.

For debugging did below steps,

1. Passed "+" value through request parameter in Connect Http rule. It takes it as blank only.
2. Passed any constant value 0,1..; it passes; but we need to pass the blank value, i.e. " "
3. Debug mode for InvokeHTTPRequest activity was made active. Focus on sessionText

Pega 5.5 log file line of request when debug is turned on for the InvokeHTTPRequest activity:

https://...sessionText=+&bus...

Pega 7 version of log output:

https://...sessionText=&bus....

Can anyone, please suggest.
