profile "' + profile.name + '" has no prose

Error message

 profile "' + profile.name + '" has no prose

What it means

renderKeywordSection renders each competitor profile as a heading plus paragraphs. Every profile must carry at least one paragraph; if profile.paragraphs is missing or empty, the build throws '<slug> profile "<name>" has no prose' so no empty competitor block reaches the generated page.

Solutions

1. Add a non-empty paragraphs array to the named competitor profile in competitorProfiles.
2. Check for typos in the field name — it must be exactly paragraphs (optional chaining hides null/undefined until this check).
3. Remove the stub profile entirely if it is not ready; partial profiles are not allowed.

Example fix

// before
competitorProfiles: [
  { name: 'Acme Risk', paragraphs: [] },
]
// after
competitorProfiles: [
  { name: 'Acme Risk', paragraphs: ['Acme Risk focuses on country risk scores with ...'] },
]

page.competitorProfiles?.forEach((p) => {
  if (!Array.isArray(p.paragraphs) || p.paragraphs.length === 0) throw new Error(`profile ${p.name} needs paragraphs`);
});

const hasProfileProse = (p) => Array.isArray(p?.paragraphs) && p.paragraphs.length > 0;

When it happens

Trigger: A page.competitorProfiles entry has no paragraphs property or paragraphs: [] when renderKeywordSection runs during COMPARISON_PAGES construction.

Common situations: Adding a new competitor profile entry and forgetting the paragraphs field; renaming paragraphs to body/text in one profile but not others; importing profiles from a data file where one entry was stubbed with an empty array.
