After upgrading from Java 8 to Java 17, encountered the following error messages when attempting to open a Job in Talend Studio 8.0.1; however, the same Job could be opened normally prior to the upgrade.

JsonIoException setting field 'flags' on target: Property: null with value: {}

Resolution

To resolve the issue, install Java 11 or upgrade Talend Studio to version 8.0.1-R2023-10 or later.

Cause

The version of Talend Studio you are currently using is prior to 8.0.1-R2023-10, and Java 17 is not a supported Java environment for versions earlier than Talend Studio 8.0.1-R2023-10, please refer to Supported Java versions for launching Talend Studio | Qlik Help Documentation.
