I worries is that (aem-spa-page-model-manager)-package has been supported for a long time on a limited version of NPM, how about trying to update it to the up-today one?
This may not be an easy task, but I believe that keeping packages up to date will help improve your product and make it more alive.
I remind you that the current version of npm is limited and has '6.14.17' and for up-today we have '8.12.1'
