I had similar issue, and I was getting html response from the endpoint instead of JSON response, but I couldn't see the html response so I enabled the following in <EI_HOME>/conf/log4j2.properties and restarted WSO2

logger.httpclient-wire-content.level=TRACE

logger.synapse-transport-http-wire.level=TRACE

logger.httpclient-wire-header.level=TRACE

After enabling logging I was able to see the response HTML which was a Support ID by Load Balancer

reference is : https://docs.wso2.com/display/EI660/Logs+in+WSO2+EI+6.6.0#LogsinWSO2EI6.6.0-Wirelogs(fortheESBprofile)

Also It's better If you enabled message formatters and message builders in deployment.toml

[[custom_message_formatters]]
content_type = "text/html"
class = "org.apache.axis2.format.PlainTextFormatter"

[[custom_message_builders]]
content_type = "text/html"
class = "org.apache.axis2.format.PlainTextBuilder"

This is most likely an HTTP page being returned by the laravel endpoint you've defined at the end. I recommend you turn on Wire logging via the config tab in the carbon console to see what exactly is being returned by the endpoint.
