Error when creating new blog post

[t14]

When creating a new blog post the following TypeError occurs

Unhandled Runtime Error

[ Server ] Error: Cannot read properties of undefined (reading 'includes')

eval
./app/blog/%5B...slug%5D/page.tsx
Module.generateMetadata
./app/blog/%5B...slug%5D/page.tsx

Checking that img is defined before calling the the includes method resolves the issue
