Bug report
Description
At the beginning of the deployment, using curl had no problems at all. But 1 day later, the API suddenly responded to an error with a message: “Call to undefined function curl_init()”. I tried several solutions in the problem report history of this repository with the same problem, but all of them did not work at all.
I tried the following:
- Changing the NodeJS version to
18.x, 20.x, 22.x
- Changed the version of
vercel-php in vercel.json with several versions: 0.7.3, 0.6.2
- Changed the use of
curl_* to file_get_contents with stream_context_create customization using the same flow
From all the experiments above, the API now does not provide any response, only a blank page with HTTP 200 status code. Actually this is a simple project to create a RESTFull API by calling the API from another server, then returning the response back to the client. Here are some code on my project:
