Property 'getType' does not exist on type 'typeof import

[Gavin Kimpson]

I am upgrading an app from Angular 12 to Angular 13 - when building I get some errors in the terminal related to mime which are below, is this something generic I need to fix or something with mime itself? The getType property exists in the class as I can control-click in my IDE and it opens the relevant code in the mime class so i'm unsure what is happening here.

Error: src/app/components/feeds/replies/reply.ts:81:31 - error TS2339: Property 'getType' does not exist on type 'typeof import("/Users/me/Sites/app-ng/node_modules/@types/mime/index")'.

81         const mimeType = mime.getType(item) || '';

ng version displays the following (if it helps)

You have to install the types as dev dependency - @types/mime
