cognee-cli -ui error

[LStromann]

=I'm new to Cognee and have just installed it, but I seem to have a problem running the Cognee-cli -ui.

I'm running python version: Python 3.12.8 and have sucessfully run the quickstart example.

Getting the following error, any help would be greatly appreciated:

Hi <@1000824268155801782> . DIUC that it throws 500 right when you open the start page?

[LStromann]

Not sure what .DIUC is? See the full log

thanks for taking a look

DIUC = "Do I understand correctly". Sorry for complex abbreviations

hi <@1000824268155801782> can you please check your node version?

this error occurs with node v25.x the current release which introduced a new localStorage API that's still being stabilized.

try switching to node v24 LTS or any version earlier than 25 and then run it again.

for more refrence you could read this - mswjs/msw#2626

thanks!

Thank you for taking a look at this. Downgrading to node v24 LTS solved the issue for me.
