I’m using axios with NodeJS to query the REST API of Mikrotik RouterOS for that you need to use self-signed SSL certificates mandatorily.
It all works fine when i run GET requests and add httpsAgent: new https.Agent({ rejectUnauthorized: false}) .
But all other methods fail and I get this error:

cause: Error: self-signed certificate in certificate chain
      at TLSSocket.onConnectSecure (node:_tls_wrap:1674:34)
      at TLSSocket.emit (node:events:518:28)
      at TLSSocket._finishInit (node:_tls_wrap:1085:8)
      at ssl.onhandshakedone (node:_tls_wrap:871:12) {
    code: 'SELF_SIGNED_CERT_IN_CHAIN'
  }

i’ve already tried setting process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = 0; but with that it gives me a 401 HTTP code with “Unauthorized” message.

const macAddress= "10-78-D2-F9-12-E7";
const byPassed= "bypassed";


axios.post(`https://192.168.8.1:8082/rest/ip/hotspot/ip-binding`,
    {
        httpsAgent: new https.Agent({ rejectUnauthorized: false}), // Allow Self-signed certificates
        auth: {
            username: "****",
            password: "*****"
          },
          headers: {
            'Content-Type': 'application/json',
        },
        content: JSON.stringify({
            "mac-address": macAddress,
            "type": byPassed,
            
        })
    },
    
    ).then(response => {
        console.log(response.data)
    }).catch(error => {
        console.log(error)
    });
