org.osgi.framework.BundleException: osgi.wiring.package=com.adobe.cq.mcm.salesforce

Sometimes when we try to deploy code, bundles may not be in active state in AEM 6.1. We can see below error message.

Error Message:
18.07.2017 23:44:01.519 *ERROR* [qtp1756110899-265] org.apache.felix.http.jetty %bundles.pluginTitle: Cannot start (org.osgi.framework.BundleException: Unresolved constraint in bundle com.aem.kishore.bundle-core [654]: Unable to resolve 654.1: missing requirement [654.1] osgi.wiring.package; (&(osgi.wiring.package=com.adobe.cq.mcm.salesforce)(version>=1.1.0)(!(version>=2.0.0))))
org.osgi.framework.BundleException: Unresolved constraint in bundle com.aem.kishore.bundle-core [654]: Unable to resolve 654.1: missing requirement [654.1] osgi.wiring.package; (&(osgi.wiring.package=com.adobe.cq.mcm.salesforce)(version>=1.1.0)(!(version>=2.0.0)))

Solution:

• Delete (or stop) the ''org.eclipse.equinox.region" bundle from the felix.
• Delete the existing custom bundle.
• Restart the server (check without restarting) and then redeploy your code bundle.

This bundle has some dependency with eclipse and should not be in AEM6.1, it was meant for AEM 6.2. But somehow it got introduced in this version.

If still issue is not resolved check this post.

AEM - Salesforce lightning component - Access-Control-Allow-Origin

When I try to access salesforce lightning components in AEM, I was not able to access the lightning script from AEM server, I got below error in browser console.

Issue:

XMLHttpRequest cannot load https://AAAAAA.lightning.force.com/lightning/lightning.out.js. 
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' 
header is present on the requested resource. Origin 'https://localhost:5544' is therefore not allowed access.

Solution:

We need to whitelist the origin i.e. our aem server in salesforce. 

• Goto salesforce.com site, click on Setup -> search for CORS
• Goto CORS console, give the AEM server url pattern, in my case it is https://localhost:5544

Adobe Salesforce Connector - INVALID_SESSION_ID

Issue:

I have integrated AEM with Salesforce using salesforce cloud config. I am able to connect to salesforce successfully and able to pull data from salesforce. After sometime when I access aem page am getting error below

[{"message":"Session expired or invalid","errorCode":"INVALID_SESSION_ID"}]  

I have also checked below settings in salesforce

• Session timeout after 4 hours of inactivity
• Selecte OAuth scopes
•  Perform requests on your behalf at any time (refresh_token, offline_access)
• Access and manage your data (api)
• Full Access (Full)

Resolution:

In sales force we need to remove Full Access (Full) OAuth Scopes, if we use this then refresh token will not be effective.

Check here how to integrate Salesforce with AEM

Salesforce REST API implementation - JAVA

This post demonstrates the following basic use cases for the REST API:
- authentication with OAuth 2.0 (This is for development purposes only. Not a real implementation.)
- querying (using account records)
- inserting (using a contact record related to one of the retrieved account records)
- updating (updates contact record added in previous step)

Salesforce: Can't refresh access token. Response: {"error":"invalid_grant","error_description":"token validity expired"}

Sometimes we may not be able to refresh the Salesforce access_token using the rest api and get below error in logs

28.03.2017 23:41:40.184 *ERROR* [0:0:0:0:0:0:0:1 [1490724696957] GET /content/training/en/salesforce/jcr:content/par/salesforcesearch.html HTTP/1.1] com.adobe.cq.mcm.salesforce.SalesforceClient Can't refresh access token. Response: {"error":"invalid_grant","error_description":"token validity expired"}

Root cause:
This issue is due to the "Refresh Token Policy" settings of the connected app is set to "Immediately expire refresh token"

Follow the below steps to resolve this issue:

• Goto setup -> Connected apps ->Manage Policies
• Select Refresh Token Policy as Refresh token is valid until revoked
