在我的 Corda 4.1 安装中,我使用签名约束并希望在我的状态中添加一个新字段“测试”。添加它并在我尝试查询我的保管库时更新我的cordapp后,我收到以下错误:
"VaultQueryException - An error occurred while attempting to query the vault: Failed to deserialise group OUTPUTS_GROUP at index 0 in transaction: Cannot construct evolution serializer for remote type sg.tradecloud.contracts.states.company.properties.Company: Mandatory property test of local type is not present in remote type. This implies the type has not evolved in a backwards compatible way. Consider making test nullable in the newer version of this type.
我有什么选择来解决这个问题?我应该让“测试”为空吗?我应该做明确的状态更新吗?或者还有其他我可以解决的吗?
