The UI was working fine 3 days ago

Peyton Runyan · Answer

I am fairly new to deveops and data engineering so my apologies if I m missing something obvious here

Zanie · Answer

Hi < Peyton Runyan> it looks like the database got created anew can you make sure a tenant has been created

Zanie · Answer

`prefect backend server amp amp prefect server create tenant name default slug default`

Zanie · Answer

it should be more than blank if the tenant is missing but I m not sure what else would cause this

Well that means one exists slightly smiling face great Can you open the developer console in your browser and see if there are error messages

Peyton Runyan · Answer

Thanks for your time on this

Zanie · Answer

Ah this looks like an issue with our new SSO work I ll ping someone who knows more

Zanie · Answer

Can you try switching to a release tag instead of the master branch The Okta code shouldn t be released yet `git checkout 0 14 5`

Peyton Runyan · Answer

oh whoops that master is my master not prefect master Here s the version installed in my venv `prefect 0 14 2+35 ge2edc8aeb`

Peyton Runyan · Answer

Just did a pip upgrade and will try now `Successfully installed prefect 0 14 5`

Peyton Runyan · Answer

that solved it thanks

Zanie · Answer

Wonderful Since the prefect version was `+35` commits ahead of a release tag it was pulling the `master` branch of the UI which is normally fine but since it s got some breaking changes right now it won t work You can override the UI tag see <https github com PrefectHQ prefect blob master src prefect cli server py L323 L331> or just make sure you re on a tagged commit of `prefect` in the future slightly smiling face

Zanie · Answer

Hi this error looks different it looks like you can t connect to your server Can you navigate to `<http localhost 4200 graphql>` in your browser

Sagun Garg · Answer

< Zanie> thanks I was able to go past this error by setting ```$export PREFECT USER CONFIG PATH= $Home prefect config toml where the $HOME I generated using the $pwd command```

Sagun Garg · Answer

But < Zanie> Now I am running into issues with creating a tenant It has been 3 days since I am unable to resolve it Based on prefect graphql container logs I think I am realizing it could be haura admin secret issue as mutations are failing while creating a tenant I am not sure which containers require ENV variable set to make it work ```prefect utilities exceptions ClientError message Errno 2 Name or service not known locations line 2 column 5 path create tenant extensions code INTERNAL SERVER ERROR exception message Errno 2 Name or service not known ```

Sagun Garg · Answer

< Zanie> Do you think this is because I am using hasura graphql engine v1 3 3 instead of hasura graphql engine v1 3 0 I see there is a breaking change mentioned by hasura repo for treatment of headers in graphql after v1 3 0 Could this actually explain why I am getting above errors v
