Hi BlueOS Community 👋

I’ve developed a custom map extension for BlueOS called **blueos-custom-map**.

**Problem**

After installing the extension via the BlueOS Extensions Manager, I’m running into two issues:

1. The extension status shows **“This extension is enabled but the container is not running”**
2. The logs panel shows **“Reconnecting to Custom Map Extension”** and keeps loading indefinitely

**What I’ve tried**

- Uninstalling and reinstalling the extension
- Checking the logs (container doesn’t produce any output)
- The extension image is hosted on Docker Hub as `haresh53/blueos-custom-map:latest`

\*\*  
Questions\*\*

1. What are the most common reasons a BlueOS container fails to start after being enabled?
2. Is there a way to see the container startup logs or crash reason beyond the Extensions Manager UI?
3. Are there any known issues with Python-based HTTP servers inside BlueOS Docker extensions?

Any help appreciated!

Hi @haresh,

Thanks for creating such cool extension!  
First, it appears that you extension is only available as x86-64, be aware that you need to provide armv7 and arm64 to make it available for the Raspberry Pi 4 (running armv7) and Raspberry 5.  
With that said, since it appears that you are running BlueOS in a X86 machine, can you provide how are you running it and the commands that you are using ?  
From the tests that I did here, it appears that you extension is not providing a register\_service file, please check the following documentation: [BlueOS Documentation](https://blueos.cloud/docs/stable/development/extensions/)
