Connection error when running integrations through Informatica Anaplan connector

You may receive the following error when trying to run an intergration to/from Anaplan using Informatica:

The test connection for ... failed. Could not initialize class okhttp3.internal.concurrent.TaskRunner

The Anaplan Engineering team are working on a fix for the issue, for now please use the below workaround to rollback to a prior version of the Anaplan connector.

Take the following steps to rollback the connector to the previous version.

1. Download the old AnaplanV2.28.zip Package from the following link and extract: https://downloads.anaplan.com/known-issues/package-AnaplanV2.28.zip

2. Take a backup of the following folder <agent_installation_directory<>\downloads\package-AnaplanV2.29 (e.g. C:\Program Files\Informatica Cloud Secure Agent\downloads\package-AnaplanV2.29)

3. Stop your secure agent from running

4. Replace the 3 items, "package folder", "Manifest.txt" and "packageInfo.xml" in the package-AnaplanV2.29 with the content from the extracted package-AnaplanV2.28 folder

5. Restart the Secure Agent.

6. In the Informatica portal, spin up a new version of Data_Integration_Server by changing any configuration such asNetworkTimeoutPeriod (runTime environments —> Select your runtime environment —>  Press Edit (top right) —> select Service ‘Data Integration Server’ —> edit the value for NetworkTimeoutPeriod)

7. Test the connection again.
