[mergify]

This pull request does not have a backport label. Could you fix it @dependabot[bot]? 🙏
To fixup this pull request, you need to add the backport labels for the needed
branches, such as:

• backport-./d./d is the label to automatically backport to the 8./d branch. /d is the digit

[mergify]

backport-v8.x has been added to help with the transition to the new branch 8.x.
If you don't need it please use backport-skip label and remove the backport-8.x label.

[pchila]

The same upgrade is included in #5492 I would rather merge that PR...

@pchila I'm guessing we need #5492 to be merged for this error to go away?
