尝试使用 POSTMAN POST REST API 上的 Hyperledger 事务时出现验证错误(错误代码 422)
Validation Error (Error Code 422) while trying to POST Hyperledger Transaction on REST API using POSTMAN
我试图通过 Playground、Composer-Rest-server 和 Finally POSTMAN 测试交易。
事务在 Playground(图 1 和 2)以及 Composer-Rest-Server(图 3 和 4)上运行良好。但是后来我尝试使用 POSTMAN 进行相同的操作,但我收到错误(状态代码 422)(图 5)。
我正在使用 basic-sample-network。而交易只是更新资产的价值。
Figure 1 - Executing Sample Transaction On Playground
Figure 2 - Updated Value of Asset #3952
Figure 3 - Executing the Transaction on the composer Rest Server
Figure 4 - Updated Value of Asset #3952 after the Rest Server Transaction
Figure 5 - Error While Using POSTMAN
错误

出现此错误的原因是什么,我该如何解决?
