2182 0 6 1 0 as_req_hdrs_content_len_exceeds_post_limit
Resolution
This is the default behavior of appfw if the request size i.e. content-length exceeds the post body limit, (default value of 20 mb) we will send the 400 error and abort the connection.
For this, we have to increase the POST Body Limit under the Profile Settings of the APPFW_PROFILE.
Problem Cause
APPFW sends a 400 error back to the client.
Issue/Introduction
