{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Example project does not work in 4.0.6 when using simwrapper run config.yaml: cannot access local variable 'e' where it is not associated with a value","articleBody":"When I try to run the [example project](https://github.com/simwrapper/simwrapper-example-project/archive/refs/heads/main.zip) using simwrapper 4.0.6 navigating to the dashboards (under `/data/dashboards/`) leads to the error:\n\n```\ncannot access local variable 'e' where it is not associated with a value\n```\n\nIn the UI this results in an error at the bottom of the screen:\n\n```\nError parsing: dashboards/4-charts-and-maps/dashboard-2-maps.yaml\n```\n\n## Steps to reproduce\n1. Create the following folder structure:\n    ```\n    |- data/\n    |---- berlin/\n    |---- dashboards/\n    |---- \u003cetc... all contents of the example project\u003e\n    |- config.yaml\n    ```\n2. Edit `config.yaml` such that it looks like this:\n    ```yaml\n    storage:\n      simwrapper:\n        path: './data'\n        description: 'Local data from this server'\n    \n    tagline: 'Config file for issue'\n    readme: |\n      Dummy text for issue\n      ====================\n    ```\n3. In the top-folder (where config.yaml resides) run: `uvx simwrapper==4.0.6 run config.yaml --debug`\n4. Open http://localhost:4999, navigate to simwrapper -\u003e dashboards -\u003e 4-charts-and-maps\n    - Or go there directly: http://localhost:4999/simwrapper/dashboards/4-charts-and-maps/\n\n\n### Expected outcome\nThe dashboard is shown, with graphs and an option in the sidebar to go to a page with maps.\n\n\u003cimg width=\"740\" height=\"382\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/1d16c863-cc92-4b61-b687-6dafbb0b44a8\" /\u003e\n\n### Actual outcome\nThe folder contents are shown in the Simwrapper \"file lister\" and an error is shown at the bottom:\n\n\u003cimg width=\"691\" height=\"501\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/190d2e15-25ad-44b8-b630-b61f1a190d2c\" /\u003e\n\nIn the commandline that is running simwrapper I see:\n\n```\nDEBUG:simwrapper:DIR simwrapper /\nDEBUG:simwrapper:DIR simwrapper /dashboards/\nDEBUG:simwrapper:GET simwrapper dashboards/4-charts-and-maps/dashboard-1-charts.yaml\ncannot access local variable 'e' where it is not associated with a value\nDEBUG:simwrapper:GET simwrapper dashboards/4-charts-and-maps/dashboard-2-maps.yaml\ncannot access local variable 'e' where it is not associated with a value\n```\n\n### Workaround\nIf I keep everything the same, but in step 3 run: `uvx simwrapper==4.0.5 run config.yaml --debug` (4.0.5 instead of 4.0.6) I get the expected outcome.\n\n## System info\n- Windows 11 24H2\n- Edge 140.0.3485.54, but also tried on Firefox 141.0.3\n\n","author":{"url":"https://github.com/b-a0","@type":"Person","name":"b-a0"},"datePublished":"2025-09-08T21:56:03.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/3/simwrapper-python-tools/issues/3"}
