SSO-URL error when starting the dev server

[StephenLHChan]

Hey,

We are running into an issue with starting the development server. The node/npm dependencies, create app are all fine. But, when running "npm run start" to start the development server, the following error showed.

OS: Windows

Node version: 16.16.0

npm version: 8.11.0

dtp-cli version: 0.88.0

Hi,

this might be caused by a wrongenvironmentUrlin dtp.config.ts. Can you please ensure the value of environmentUrl follows the pattern https://<environment-id>.apps.dynatrace.com, e.g. environmentUrl: "https://abc123.apps.dynatrace.com"?

[StephenLHChan]

Thanks Stefan. 

The environmentalUrl  follows the pattern you mentioned.

I did not change anything. But, it works now.

Hi,

The SSO-URL error pops up again today.

I saw there is a line "Resolved URL" in the successful case while it can't be found in the fail case.

@michael_taylor This is the case I shared in Wednesday 10:30 session. The SSO-URL error happens again today.

Thanks all.

We found out it may be a company proxy issue.

Hey @heramb_sawant ,

We set the proxy at the machine that run the app for development.

export HTTP_PROXY=<your proxy>
export HTTPS_PROXY=<your proxy>
