From time to time you could experience BPErrorUnknownLabel, BPUnusedStrFmtArgument or other best practice errors related to label files, even if the label is correct and displayed properly in the UI. Typically this happens when new label is created or latest code with updated label file pulled from version control.
The solution is to run the following command from the command prompt to re-compile label files:
K:\AosService\PackagesLocalDirectory\bin\labelc.exe -metadata="K:\AosService\PackagesLocalDirectory" -output="K:\AosService\PackagesLocalDirectory\your_model_name\Resources" -modelmodule="your_model_name"
