Hi,&lt;br&gt;<br>
I&nbsp;have&nbsp;a&nbsp;rest&nbsp;handler&nbsp;that&nbsp;accepts&nbsp;POST&nbsp;and&nbsp;PUT&nbsp;requests&nbsp;with&lt;br&gt;<br>
“application/json”&nbsp;content&nbsp;type.&lt;br&gt;<br>
&lt;br&gt;<br>
I&nbsp;have&nbsp;content_types_accepted&nbsp;function&nbsp;defined&nbsp;as&nbsp;follows:&lt;br&gt;<br>
&lt;br&gt;<br>
content_types_accepted(Req,&nbsp;State)&nbsp;-&gt;&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;<br>
{[{‘application/json&#39;,&nbsp;from_json}],&nbsp;Req,&nbsp;State}.&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;<br>
The&nbsp;problem&nbsp;I&nbsp;have&nbsp;is&nbsp;within&nbsp;a&nbsp;request&nbsp;that&nbsp;has&nbsp;two&nbsp;headers:&lt;br&gt;<br>
&lt;br&gt;&lt;/div&gt;<br>
*Content-type*:&nbsp;application/json&lt;br&gt;<br>
*Accept*:&nbsp;application/json&lt;br&gt;<br>
&lt;br&gt;<br>
With&nbsp;this&nbsp;combination&nbsp;I&nbsp;receive&nbsp;*406*.&lt;div&nbsp;class=&quot;im&quot;&gt;&lt;br&gt;<br>
&lt;br&gt;<br>
You&nbsp;can&nbsp;repeat&nbsp;it&nbsp;with&nbsp;test:&lt;br&gt;<br>
&lt;br&gt;<br>
http_SUITE.erl:&lt;br&gt;<br>
1072&nbsp;rest_postonly(Config)&nbsp;-&gt;&lt;br&gt;<br>
1073&nbsp; &nbsp; &nbsp;Client&nbsp;=&nbsp;?config(client,&nbsp;Config),&lt;br&gt;<br>
1074&nbsp; &nbsp; &nbsp;Headers&nbsp;=&nbsp;[&lt;br&gt;<br>
1075&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;{&lt;&lt;&quot;content-type&quot;&gt;&gt;,&nbsp;&lt;&lt;&quot;text/plain&quot;&gt;&gt;},&lt;br&gt;<br>
1076&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;{&lt;&lt;&quot;accept&quot;&gt;&gt;,&nbsp;&lt;&lt;&quot;text/plain&quot;&gt;&gt;}&lt;br&gt;<br>
1077&nbsp; &nbsp; &nbsp;],&lt;br&gt;<br>
1078&nbsp; &nbsp; &nbsp;{ok,&nbsp;Client2}&nbsp;=&nbsp;cowboy_client:request(&lt;&lt;&quot;POST&quot;&lt;u&gt;&lt;/u&gt;&gt;&gt;,&lt;br&gt;<br>
1079&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;build_url(&quot;/postonly&quot;,&nbsp;Config),&nbsp;Headers,&nbsp;&quot;12345&quot;,&nbsp;Client),&lt;br&gt;<br>
1080&nbsp; &nbsp; &nbsp;{ok,&nbsp;204,&nbsp;_,&nbsp;_}&nbsp;=&nbsp;cowboy_client:response(&lt;u&gt;&lt;/u&gt;Client2).&lt;br&gt;<br>
&lt;br&gt;<br>
My&nbsp;solution&nbsp;to&nbsp;that&nbsp;was&nbsp;to&nbsp;add&nbsp;a&nbsp;content_types_provided&nbsp;function:&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;<br>
content_types_provided(Req,&nbsp;State)&nbsp;-&gt;&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;<br>
ContentTypes&nbsp;=&nbsp;[{{&lt;&lt;&quot;application&quot;&gt;&gt;,&nbsp;&lt;&lt;&quot;json&quot;&gt;&gt;,&nbsp;&#39;*&#39;},&nbsp;to_json}],&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;<br>
{ContentTypes,&nbsp;Req,&nbsp;State}.&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;&lt;/div&gt;<br>
But&nbsp;it&nbsp;is&nbsp;useless&nbsp;as&nbsp;*to_json*&nbsp;callback&nbsp;registered&nbsp;is&nbsp;not&nbsp;called&nbsp;anyhow.&lt;br&gt;<br>
&lt;br&gt;<br>
Adding&nbsp;*content_types_provided*&nbsp;function&nbsp;is&nbsp;a&nbsp;correct&nbsp;solution&nbsp;in&nbsp;this&nbsp;case?&lt;div&nbsp;class=&quot;im&quot;&gt;&lt;br&gt;<br>
Or&nbsp;I&nbsp;am&nbsp;missing&nbsp;something&nbsp;here?&lt;br&gt;<br>
“Accept”&nbsp;header&nbsp;is&nbsp;not&nbsp;relevant&nbsp;only&nbsp;in&nbsp;case&nbsp;of&nbsp;GET&nbsp;requests?&lt;br&gt;<br>
&lt;br&gt;<br>
Thank&nbsp;for&nbsp;help,&lt;br&gt;<br>
