Airtable script sends OPTIONS instead of POST, triggering 405 errors. See revised client and server examples below:
// Airtable client script example
let recordTable = base.getTable('UserRecords');
const entries = await recordTable.selectRecordsAsync();
let currentEntry = entries.records[0];
let payload = { first: currentEntry.getCellValue('firstName'), last: currentEntry.getCellValue('lastName'), email: currentEntry.getCellValue('email') };
let result = await fetch('https://example.com/hook', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(payload) });
console.log(await result.json());
// Node.js backend handler example
export default async function processReq(req, res) {
if (req.method === 'POST') {
res.status(200).json({ message: 'Processed' });
} else if (req.method === 'OPTIONS') {
res.setHeader('Allow', 'POST');
res.status(405).end(`Method ${req.method} Denied`);
}
}
maybe issue is due to cors preflight. try enabling cors on your server to allow OPTIONS so that your post goes thru. also check that headers include access-control-allow-origin, etc.
i had a similar prob because my route mappings clashed - the post req was missing its intended target. checking server routing configs and ensuring the endpoint exactly matches solved it for me. hope this helps!
I encountered a similar issue when integrating a third-party client with my Node.js API. The initial problem was indeed related to the preflight request that browsers automatically send. In my case, implementing stricter CORS handling on the server resolved the error. I enhanced the middleware logic to correctly process the OPTIONS method without triggering 405 errors, which made the subsequent POST request behave as expected. Adjusting the headers and ensuring the server responded properly to preflight calls were key steps to remedying the situation in my project.
I encountered a similar issue when working with an Airtable script integration while developing a custom API. After some debugging, I discovered that the problem was not entirely with CORS handling itself, but also with the server environment configuration. In my case, an intermediary service was intercepting and modifying the requests, and the API endpoint was not set up to correctly manage these unexpected OPTIONS calls. Adjusting the hosting settings to better accommodate the network behavior and ensuring that the server logic acknowledged preflight requests resolved the issue on my side.
Through my experience, I found that ensuring consistent server configuration is key. My investigation revealed that even if the CORS headers were set correctly, subtle details like the API endpoint match and handling of the OPTIONS preflight could cause issues. Adjusting the code to explicitly handle the OPTIONS method and returning the necessary headers solved the problem in my case. It is also worthwhile to double-check any intermediary network settings, such as proxy or firewall configurations, which might inadvertently modify the requests. This thorough review of both client and server setups ensured the POST request processed correctly.
