Acces Pinia store inside of a Typscript class

[etarno03]

Hi there,
I was trying to use a Pinia store inside of a Typescript class but i get this error

Uncaught Error: [🍍]: getActivePinia was called with no active Pinia. Did you forget to install pinia? const pinia = createPinia() app.use(pinia) This will fail in production.

any suggestions?
thx.

You might be missing the pinia install, as the message suggests, or you are using a store before that like in https://pinia.vuejs.org/core-concepts/outside-component-usage.html
