@GetMapping Required String parameter is not present

[programingMa]

now i get a spring-boot-server(server-a) invoke other(server-b) though feign.
Then there is an error. for detail see attach plz.
don't why.
but this error is not inevitably appearing.
seems like when many threads invoke importFacade.status(fileId) this error appeared frequently.
thanks for your help.
