This pull request does not have a backport label. If this is a bug or security fix, could you label this PR @jonathan-albrecht-ibm? 🙏. For such, you'll need to label your PR with:

• The upcoming major version of the Elastic Stack
• The upcoming minor version of the Elastic Stack (if you're not pushing a breaking change)

To fixup this pull request, you need to add the backport labels for the needed branches, such as:

• backport-8./d is the label to automatically backport to the 8./d branch. /d is the digit
• backport-active-all is the label that automatically backports to all active branches.
• backport-active-8 is the label that automatically backports to all active minor branches for the 8 major.
• backport-active-9 is the label that automatically backports to all active minor branches for the 9 major.

@jonathan-albrecht-ibm Thanks! Can you run make check and commit the changes to the python file? It looks like CI is probably failing on some formatting requirements.

Thanks @mauri870 and @faec. I have fixed the formatting.
