async deleteCollection(name: string): Promise<void> { try { console.log('Attempting to delete Qdrant collection using direct fetch...'); // Use direct fetch instead of the client const deleteUrl = `${this.url}/collections/${name}`; console.log(`Fetching from: ${deleteUrl}`); const response = await fetch(deleteUrl, { method: 'DELETE', headers: { 'Content-Type': 'application/json', ...(this.apiKey ? { 'api-key': this.apiKey } : {}) }, // @ts-ignore - node-fetch supports timeout timeout: 5000 // 5 second timeout }); if (!response.ok) { throw new Error(`HTTP error!
