[BUG] Custom proxy with error "Expecting a valid host string in proxy settings, but found"

[hintdesk]

Description/Screenshot In my company we have set a corporate proxy. To connect to Internet the application has to use this proxy. The proxy has the format of "proxy.companyname.i:port". I have set that proxy over env variable http_proxy und https_proxy. Currently I receive this error

Configuring Azure AppInsights Failed to start default client: [object Error]{ stack: 'Error: Expecting a valid host string in proxy settings, but found "proxy.companyname.i". 2024-05-15T13:03:52.037201912Z at getUrlFromProxySettings (/app/node_modules/@azure/core-rest-pipeline/dist/commonjs/policies/proxyPolicy.js:129:15) at proxyPolicy (/app/node_modules/@azure/core-rest-pipeline/dist/commonjs/policies/proxyPolicy.js:177:11) 2024-05-15T13:03:52.037210399Z at createPipelineFromOptions (/app/node_modules/@azure/core-rest-pipeline/dist/commonjs/createPipelineFromOptions.js:30:61) at createClientPipeline (/app/node_modules/@azure/core-client/dist/commonjs/pipeline.js:16:73) at createDefaultPipeline (/app/node_modules/@azure/core-client/dist/commonjs/serviceClient.js:157:51) at new ServiceClient (/app/node_modules/@azure/core-client/dist/commonjs/serviceClient.js:53:45) at new ApplicationInsightsClient (/app/node_modules/@azure/monitor-opentelemetry-exporter/dist/index.js:1824:9) 2024-05-15T13:03:52.037227236Z at new HttpSender (/app/node_modules/@azure/monitor-opentelemetry-exporter/dist/index.js:2782:34) at new AzureMonitorMetricExporter (/app/node_modules/@azure/monitor-opentelemetry-exporter/dist/index.js:3591:24) at new MetricHandler (/app/node_modules/@azure/monitor-opentelemetry/dist/index.js:3220:31)', message: 'Expecting a valid host string in proxy settings, but found "proxy.companyname.i".', name: 'Error' [] AppInsights ProxyHttpUrl: http://proxy.companyname.i:port AppInsights new ProxyHttpUrl: http://proxy.companyname.i:port `

Steps to Reproduce

• SDK Version [e.g. 22]: 3.0.0
• How you initialized the SDK:

if (process.env.APPLICATIONINSIGHTS_CONNECTION_STRING) { console.log('Configuring Azure AppInsights'); appInsights .setup(process.env.APPLICATIONINSIGHTS_CONNECTION_STRING) .setAutoDependencyCorrelation(false) .setAutoCollectRequests(true) .setAutoCollectPerformance(false, false) .setAutoCollectExceptions(true) .setAutoCollectDependencies(false) .setAutoCollectConsole(false) .start(); }

Expected behavior What should I have to do to tell ApplicationInsights SDK that "proxy.companayname.i:port" is a valid host?
