Implementation Reference
- The core handler function `executeFunction` that performs the HTTP PUT request to the Google Apps Script API to update project content. Handles OAuth token retrieval, request construction, API call, error handling, and logging.const executeFunction = async ({ scriptId, files }) => { const baseUrl = 'https://script.googleapis.com'; const startTime = Date.now(); try { logger.info('SCRIPT_UPDATE_CONTENT', 'Starting script content update', { scriptId, filesCount: files?.length || 0 }); // Get OAuth access token const token = await getOAuthAccessToken(); // Construct the URL for the request const url = `${baseUrl}/v1/projects/${scriptId}/content`; // Set up headers for the request const headers = { 'Authorization': `Bearer ${token}`, 'Content-Type': 'application/json', 'Accept': 'application/json' }; // Prepare the body of the request const requestBody = { scriptId, files }; const body = JSON.stringify(requestBody); logger.logAPICall('PUT', url, headers, requestBody); // Perform the fetch request const fetchStartTime = Date.now(); const response = await fetch(url, { method: 'PUT', headers, body }); const fetchDuration = Date.now() - fetchStartTime; const responseSize = response.headers.get('content-length') || 'unknown'; logger.logAPIResponse('PUT', url, response.status, fetchDuration, responseSize); // Check if the response was successful if (!response.ok) { const errorText = await response.text(); let errorData; try { errorData = JSON.parse(errorText); } catch (parseError) { errorData = { message: errorText }; } const detailedError = { status: response.status, statusText: response.statusText, url, errorResponse: errorData, duration: Date.now() - startTime, scriptId, filesCount: files?.length || 0, timestamp: new Date().toISOString() }; logger.error('SCRIPT_UPDATE_CONTENT', 'API request failed', detailedError); console.error('❌ API Error Details:', JSON.stringify(detailedError, null, 2)); throw new Error(`API Error (${response.status}): ${errorData.error?.message || errorData.message || 'Unknown error'}`); } // Parse and return the response data const data = await response.json(); logger.info('SCRIPT_UPDATE_CONTENT', 'Successfully updated script content', { scriptId, filesCount: files?.length || 0, duration: Date.now() - startTime }); console.log('✅ Successfully updated script content'); return data; } catch (error) { const errorDetails = { message: error.message, stack: error.stack, scriptId, filesCount: files?.length || 0, duration: Date.now() - startTime, timestamp: new Date().toISOString(), errorType: error.name || 'Unknown' }; logger.error('SCRIPT_UPDATE_CONTENT', 'Error updating script project content', errorDetails); console.error('❌ Error updating script project content:', errorDetails); // Return detailed error information for debugging return { error: true, message: error.message, details: errorDetails, rawError: { name: error.name, stack: error.stack } }; } };
