I encountered a similar issue when sending MQTT messages using AWS IoT. The error message was "PKIX path building failed."

I eventually found out that the API I was using was actually defaulting to HTTP instead of HTTPS for communication. Once I configured it to use HTTPS, the problem was resolved.

thecode as follows:

            return IotDataPlaneClient.builder()
            .region(Region.of(region))
            .credentialsProvider(StaticCredentialsProvider.create(credentials))
            // here  https!!!!!
            .endpointOverride(URI.create("https://xxxxxx"))
            .build();

This error usually occurs when the server expects a certificate, but the client does not provide one, or the provided certificate does not match the certificate configured on the server side.

I found this blog post that AWS created which explains how to fix the issue:
