Bootstrap5 from bootstrap4 bs.tooltip error

I have this error:

I have searched for every instance of bs.tooltip and removed them from all of the components.
The error message does not go away so there must be 1 lurking somewhere.

I created several charts in the bs4 version and have not changed or edited them since changing to BS5…
Would this be causing the error.
Or is there something else I need to look at?

Thanks
