Facing issue while deploying SonarQube DCE using Helm Chart

We are trying to deploy SonarQube DCE using Helm chart. We are facing following error:

Error: INSTALLATION FAILED: execution error at (sonarqube-dce/templates/validation.yaml:8:4):
** The values.yaml file is not valid. **
You must set a value for either “jwtSecret” or “existingJwtSecret”, but not both.

We export jwtSecret on linux, and not added in values.yaml. We followed steps mentioned in SonarQube Document. But still facing issue. Please help me to resolve.

Please review the installation instructions provided in the documentation. When deploying your chart, ensure that you include the following parameters to set the required secrets:

--set applicationNodes.jwtSecret=$JWT_SECRET --set monitoringPasscode=$MONITORING_PASSCODE
