IClusterMember::GetMetadataAsync throwing exceptions when used with IRaftHttpCluster

[Arkensor]

Hi,

I am currently trying to use the Raft feature, and got members to join a cluster. However when I try to get their metadata via GetMetadataAsync the receiving instance (who is also the leader) just throws a middleware exception about not being able to properly handle the json data that is used internally to communicate.

I have tried setting no meta data, I have tried setting a simple "hello" -> "world" pair, nothing seems to make a difference.

Can someone please check if this function is currently working for them? I am using the latest stable release 4.1.3

Thank you!

This is all the information given to me. Visual studio is unable to catch the error, there is no more output besides this:

Hello @sakno,

thank you for your quick reply! Great news knowing you could fix it. Do you know when this will be released via nuget? Is there some regular release period?

[sakno]

There is no period for regular releases. I expect to release it in this month to include other fixes.
