Axios, https and self-signed certificates

Hi, I’m using axios from vue typescript over https to a web api that returns a self signed cert, but I can’t get axios to ignore cert errors that are then reported by the browser. I have tried suggestions from other posts (that have now been closed) as follows below but just get cert errors reported in the console and nothing on the page until I accept the cert from the console (chrome and FF, Edge won’t do anything and needs Fiddler).

Here is the a snippet from main.ts…

axios.interceptors.request.use((config) => {
    const https = require('https');
    // https.globalAgent.options.rejectUnauthorized = false;  // doesn't work, options is undefined.
    config.httpsAgent = new https.Agent({ rejectUnauthorised: false }); 
    config.baseURL = 'https://addr/';
    return config;
},
    (err) =>
    {
        console.log('AXIOS Interceptor: Error returned: ' + err);
    });

This is from home.vue because the main,ts interceptor code doesn’t work…

	async getInfo(siteCode: string): Promise<any> {

                const infoEndpoint = 'site-by-code/' + siteCode;
                const https = require('https');
                try
                {
                    const agent = new https.Agent({
                        rejectUnauthorized: false,
                    });
                    const response = await this.$http.get(this.serviceBase + infoEndpoint, { httpsAgent: agent });
                    return response.data;
                } catch (err) {
                    console.log(err);
                }
                return null;
           },

Cheers.
