Questions about FIDO2 Server - MDS3 : Metadata service test in conformance tool

[John Hsu]

Hello guys,

Sorry for another simple question about test tool.

A few weeks ago, our sever was able pass the part of metadata test in the tool, 

but today I check it again with same version and same tool, all six test cases in the metadata service test failed, below screen shut is one part of them:   

It seems like a simple JSON problem to fix, but the real problem is our sever didn't get any message form tool, so sever won't return anything back and causing this issue.

Just a personal guess, one possibility is that when the test case called "getMDSMetadataForTestCase()", for some unknown reason, MDS return a bad JSON message to tool, then issue just happened(if the function will fetch MDS).

Does anyone have this problem? I'm not sure how to fix it.

Regards

John
