Consequences of File Editing Mistakes
If the file tileproviders.json is not properly configured, for example if a quote character or comma or curly bracket is missing anywhere, then only the Panopticon default map tile provider will be available.
The server log will display any of the following warnings:
- Unexpected end-of-input: expected close marker for Object
- Illegal unquoted character
- Cannot construct instance of `com.panopticon.server.core.web.repository.file.SettingFileRepository$TileProviders`
- Unexpected character ('{' (code 123)): was expecting double-quote to start field name
These are some examples of map tile providers:
