Thank you for report @GHostlyFOX

Please provide more details What version of PHP you're using? Does the error appear after updating the Elastic agent?

Best regards, Pawel

The code line in question is https://github.com/elastic/apm-agent-php/blob/7a7b0e0921d32679b1ef850585ca441624fc39ed/agent/php/ElasticApm/Impl/AutoInstrument/CurlHandleWrappedTrait.php#L103

According to https://www.php.net/manual/en/function.is-resource.php:

Note: is_resource() is not a strict type-checking method: it will return false if value is a resource variable that has been closed.

So it's possible that is_resource($this->curlHandle) returned false because $this->curlHandle is already closed.
