Request body with invalid JSON results in a 500 Internal Server Error response

[malta895]

Describe the bug

Performing a PATCH request to an endpoint protected by a Rond policy results in a 500 Internal Server Error if:

• the Content-Type is application/json
• the body contains an invalid JSON, with syntax errors.

The behavior has been observed on a PATCH request, but it's likely that any other http verb has the same issue.

Expected behavior

A 400 Bad Request error clearly explaning that the JSON in the body is invalid.

Actual Behavior

The server responds with a 500 Internal Server error and the following body:

{
	"error": "failed to create rond input",
	"message": "Internal server error, please try again later",
	"statusCode": 500
}

Replication info

• Rönd version: Latest (main)
• Running mode: sidecar/standalone

[fredmaggiowski]

I'd expect rönd to reply with something like

{
	"error": "malformed body",
	"message": "Bad request, the request body is invalid",
	"statusCode": 400
}
