two way SSL with MLE respone: API Internal Error: 2001. JSON string was not well formed

[Kepler]

When I am using MLE for PAV API, the request body is like {"encData":"XXX"}

I came across error: API Internal Error: 2001. JSON string was not well formed . The X-CORRELATION-ID is 1698310199_522_1824083587_b9f55w85_VDP_WS, I am not sure if there is anything wrong with encryption, can you please help take a look?

Hi @SandraW , there is no code change, I ran it again,, but the error code changed to the following one: {"status":"INTERNAL_SERVER_ERROR","code":"NPPS007","message":"Internal error occured"},

And the new X-CORRELATION-ID is 1698419670_371_231789273_-59699695_VDP_WS.

Can you please help check what this error is? and why the error code changes as I have no code change
