'Unable to determine valid runtime version number from release channel URL:' can be output to the RVM, rvm.log, file following a failed application launch.
The application provider specifies the Runtime version in the Application Configuration, and they have the option to configure either a specific runtime version or a named 'Channel'.
OpenFin recommends that specific runtime versions are configured in the application configuration to avoid conflicts in all environments.
- The channel specified in the application configuration is not available on the assets URL
- To avoid potential conflicts with internally hosted assets server we recommend the application owner configures a specific Runtime in the application configuration file.
