it doesn't work like that

SyntaxError: /Users/bjoern/projects/inventhora/frontend/pages/es/partner/[id]/index.tsx: Unexpected token, expected "," (9:31)

   7 | const namespaces = { 'common': ns0, 'table': ns1 }
   8 | 
>  9 | export default function Page(p as any){
     |                                ^
  10 |   return (
  11 |     <I18nProvider lang="es" namespaces={namespaces} >
  12 |       <C {...p} />

it should be like this:

SyntaxError: /Users/bjoern/projects/inventhora/frontend/pages/es/partner/[id]/index.tsx: Unexpected token, expected "," (9:31)

   7 | const namespaces = { 'common': ns0, 'table': ns1 }
   8 | 
>  9 | export default function Page(p: any){
     |                                ^
  10 |   return (
  11 |     <I18nProvider lang="es" namespaces={namespaces} >
  12 |       <C {...p} />
