Connect REST and Service REST
team,
Can anyone help on below issue.
We have Service RESt and Connect REST built. when we running Service REST in Service Contact with Request JSOn it is working firn. but when we are trying to hit with connect-rest we are getting error message as
| Error mapping incoming response to .Test: org.codehaus.jackson.JsonParseException: Unexpected character ('R' (code 82)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') at [Source: java.io.StringReader@4678aa54; line: 1, column: 2] |
Even we are not able to trace ServiceRest rule when we are triggerring from Connect-REST i.e., nothing is traced. is this some related to Connectivity Issue or any issue is building Connect REST Rule

What is the URL you use to log into designer studio? If you are logging into a tenant, there must be a tenant hash in the URL after prweb/PRServlet.

May I know the PRPC version?
If version is PRPC7.1.8

STEPS TO REPRODUCE
Use Connect-REST and try to pass special characters.
RESOLUTION
Apply Hotfix-24502

There are no special Chars and when we run Service manually in Service Requestor Context it is working Fine. So I have doubt whether there is any Connectivity issue with the EndPoint. Also the version is 7.1.6

Perhaps there is an exception on the service side and your service was returning an error which isn't in JSON format? Hence you see the exception during mapping of incoming response. To identify the root cause, dump the entire response onto a single-value property or a parameter on the parameter page using Map to as Clipboard instead of JSON on your Connect REST rule. Log the response and check if the response is as expected and that it is valid JSON.

here Service rule is not tracing (Trace open Rule) any thing when hit through COnnect-REST it is empty.But its fine when run manually. Also I tried through external REST Clients (Google Plug-In POSTMAN REST Client) then it is giving the below error
Request URI must contain tenant Hash, service package, class, and method keys
The EndPoint used is below it is Pega PDn Cloud where the Service is hosted
"https://paex15-eu.pegacloud.com/prweb/PRRestService/TestRest/Temp/TestServiceRest"

From the error, it looks like the URL you are hitting from your Connect REST rule is incorrect. The correct URL format when invoking a REST service created in a tenant is:
https(s)://<host>:[port]/prweb/PRRestService/<tenant-hash>/<service-package>/<service-class>/<service-method>
You need to include tenant hash in the URL, after PRRestService and before service package name.

What is this <tenant-hash> what is the purpose(valu in general it would be ) and as far as previous developments we never included this SERVICE REST ENDPOINT.
Also this error came when triggered from External Client not from CONNECT-REST.

You must have received the same error when you invoked Connect REST. This is your response:
"Request URI must contain tenant Hash, service package, class, and method keys"
You have Map to configured as JSON in your connect REST. Since this error response isn't in JSON, you get this exception (notice the R in bold below, this is the R from Request URI...):
Error mapping incoming response to .Test: org.codehaus.jackson.JsonParseException: Unexpected character ('R' (code 82)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') at [Source: java.io.StringReader@4678aa54; line: 1, column: 2]

Also previously when we are working with these service we never included but it still used to work. How is it different here in Pega PDN Cloud?

Usually the URL format is a good indicator. The tenant hash in the URL is mandatory to log into a tenant. The Pega PDN Cloud instance must be a multi-tenant set up. That's why you ran into this issue. Always try to retrieve your Service REST URL from the service package. I guess the links to the services on the service package rule have the tenant hash included if you are logged into a tenant.

When you open the service package, check the endpoint column. There is a link to each service in the service package.

This error occurs whenever you are passing any wrong or null input as a parameter which are required to connect with the service. Try to give all correct input as a parameter.
