Hello @Robert Mann
The error message you shared indicates that the 'blob' binding type was not found in the configured extension bundle. This can happen if the extension bundle version is not compatible with the 'blob' binding type or if the extension bundle is not installed correctly.
Based on the host.json file you provided, it seems that you are using version 2.0 of the Azure Functions runtime and version [3.*, 4.0.0) of the extension bundle. However, it is possible that the extension bundle was not installed correctly or that there was an issue with the Azure Functions runtime.
To prevent this issue from happening again, you can try the following steps:
- Check the Azure Functions runtime version and make sure it is compatible with the extension bundle version you are using.
- Check that the extension bundle is installed correctly and that all required extensions are included.
- If the issue persists, you can try updating the extension bundle to a newer version or downgrading to a previous version that is known to work with the 'blob' binding type.
That should get you started.
