As it notes there, you’re using a development version so the UI isn’t prebuilt. You’d need to run

prefect dev build-ui

i ran prefect dev build-ui in linux enviorment prefect/ui/node_modules/vite/bin/vite.js:7 await import('source-map-support').then((r) => r.default.install()) ^^^^^ SyntaxError: Unexpected reserved word at Loader.moduleStrategy (internal/modules/esm/translators.js13318) at async link (internal/modules/esm/module_job.js4221) Traceback (most recent call last): File "/home/edisonai/mandole/prefect/prefect/src/prefect/cli/_utilities.py", line 41, in wrapper return fn(*args, **kwargs) File "/home/edisonai/mandole/prefect/prefect/src/prefect/cli/dev.py", line 162, in build_ui subprocess.check_output( File "/usr/lib/python3.10/subprocess.py", line 420, in check_output return run(*popenargs, stdout=PIPE, timeout=timeout, check=True, File "/usr/lib/python3.10/subprocess.py", line 524, in run raise CalledProcessError(retcode, process.args, subprocess.CalledProcessError: Command '['npm', 'run', 'build']' returned non-zero exit status 1.

Also when i ran prefect server start i am getting SSL certification issue : _ _ _ _ _ _ _____ | _ \ _ \ __| __| __/ _| _| | _/ / _|| _|| | (_ | | |_| |_|_\___|_| |___\___| |_| Configure Prefect to communicate with the server with: prefect config set PREFECT_API_URL=http://127.0.0.0:4200/api View the API reference documentation at http://127.0.0.0:4200/docs The dashboard is not built. It looks like you're on a development version. See

Please let me know how can i fix this issue and able to access prefect ui

?

or node, perhaps.

i tried to upgrade npm but it didnt worked

Which node version are you using?

Also could you please tell me how can i solve this prefect.server.services.telemetry - Failed to send telemetry: [SSL: CERTIFICATE_VERIFY_FAILED] error

I’m not sure what’s going on with your SSL setup

You can also just ignore it

while installing Prefect on Linux need to configure SSL certificate https://docs.prefect.io/getting-started/installation/

As I don't want to configure SSL certificate now , as per documentation PREFECT_API_TLS_INSECURE_SKIP_VERIFY need to set True

could you please where exactly i need to set this variable as True

prefect agent Local start --env PREFECT_API_TLS_INSECURE_SKIP_VERIFY= True this is crct way to set env variable right

?
