Implementation Reference
- Main handler function that performs the HTTP GET request to retrieve a specific version of a Google Apps Script project.
const executeFunction = async ({ scriptId, versionNumber, fields, alt = 'json', key, access_token, quotaUser, oauth_token, callback, prettyPrint = true }) => { const baseUrl = 'https://script.googleapis.com'; const token = process.env.GOOGLE_APP_SCRIPT_API_API_KEY; const url = new URL(`${baseUrl}/v1/projects/${scriptId}/versions/${versionNumber}`); // Append query parameters const params = new URLSearchParams({ fields, alt, key, access_token, quotaUser, oauth_token, callback, prettyPrint: prettyPrint.toString(), '$.xgafv': '1', upload_protocol: 'raw', uploadType: 'media' }); // Set up headers for the request const headers = { 'Accept': 'application/json' }; // If a token is provided, add it to the Authorization header if (token) { headers['Authorization'] = `Bearer ${token}`; } // Perform the fetch request try { const response = await fetch(`${url}?${params.toString()}`, { method: 'GET', headers }); // Check if the response was successful if (!response.ok) { const errorData = await response.json(); throw new Error(errorData); } // Parse and return the response data const data = await response.json(); return data; } catch (error) { const errorDetails = { message: error.message, stack: error.stack, scriptId, versionNumber, timestamp: new Date().toISOString(), errorType: error.name || 'Unknown' }; logger.error('VERSION_GET', 'Error retrieving script version', errorDetails); console.error('❌ Error retrieving script version:', errorDetails); // Return detailed error information for debugging return { error: true, message: error.message, details: errorDetails, rawError: { name: error.name, stack: error.stack } }; } }; - Tool definition object containing the schema for inputs (parameters with types, descriptions, required fields) and references the handler function.
