Hello,

   Verify the connection details: Double-check that the database and owner information you entered in the Presto connector settings are correct. Ensure that you have the necessary permissions to access the specified database.

Check the compatibility: Make sure that the version of Presto you are using is compatible with the version of the Presto connector in Qlik Sense Enterprise. Check the documentation or release notes for any known compatibility issues.

Review the connection settings: Go through the connection settings in the Presto connector Pay My Doctor Login and ensure that all the required parameters, such as host, port, username, password, etc., are correctly configured.

Test the connection: Use external tools or command-line utilities to verify if you can connect to the Presto database using the provided connection details. This step will help determine if the issue is specific to Qlik Sense or related to the database itself.

Update Qlik Sense and the connector: Ensure that you are using the latest version of Qlik Sense Enterprise and the Presto connector. Upgrading to the latest versions might resolve any known issues or bugs.

Consult Qlik Support: If the issue persists, it's recommended to reach out to Qlik support for further assistance. They can provide you with specific guidance based on the version and configuration of your Qlik Sense deployment.

By following these,

you should be able to troubleshoot the JSON parsing error you encountered and hopefully resolve the issue.
