The Javascript asset-transfer-basic chaincode stores AppraisedValue and Size as string types instead of number types. This leads to an issue when used with a Go client application where assets are unmarshaled into an Asset type where AppraisedValue and Size are of uint64 type. This change makes sure that AppraisedValue and Size are stringified as numbers. To prevent the pipeline from failing when the expected error occurs a sentinel error was created and checked against in the entry point. Signed-off-by: Stanislav Jakuschevskij <stas@two-giants.com>
