[CodyxKarthi]

My Language File:

"fileLockedbyOtherUser" : "The file is currently locked by {{user}} and cannot be modified.",

while throwing exception, i want to pass arguments dynamically,

throw new PreconditionFailedException({
statusCode: ENUM_FILESTORE_STATUS_CODE_ERROR.FILE_LOCKED_BY_OTHERUSER,
message: 'filestore.error.fileLockedbyOtherUser',
});

but how to pass argument?
