Ansible task Disable pop-ups fails with Docker container splunk:9.2.1

[Qaekho]

When we start official Docker container image splunk/splunk:9.2.1 with extra var SPLUNK_DISABLE_POPUPS=true

docker run -d -p 8000:8000 -e "SPLUNK_START_ARGS=--accept-license" -e "SPLUNK_PASSWORD=OUR_PASS" -e "SPLUNK_DISABLE_POPUPS=true" --name splunk splunk/splunk:9.2.1

The Ansible task Disable Popups fails, with this error message:

Because of this the container fail to start.

When the Disable Popups variable is not given Splunk starts without issue.

Other Docker image versions, like splunk/splunk:9.2 doesn't have this issue.

Any help is appreciated.
