curl -X POST \
https://whatfix.atlassian.net/wiki/rest/api/content \
-H 'Content-Type: application/json' \
-H 'cache-control: no-cache' \
-d '{
"type": "page",
"title": "My Test Page 15",
"version":{{"number":"1" }},
"body": {
"storage": {
"value": "<ac:structured-macro ac:name=\"html\" ac:schema-version=\"1\" ac:macro-id=\"74c5d460-d9c1-4259-9489-5ca2cea8314c\"><ac:plain-text-body><![CDATA[<div><ul><li><a href=\"#Domain1\">Domain1</a></li><li><a href=\"#Domain2\">Domain2</a></li><li><a href=\"#Domain3\">Domain3</a></li><li><a href=\"#Domain4\">Domain4</a></li><li><a href=\"#Domain5\">Domain5</a></li></ul></div><br/><div><table> <colgroup><col/><col/></colgroup><tr><th>Domain</th><th>System Count</th></tr><tr><td>Domain1</td><td>653</td></tr><tr><td>Domain2</td><td>2</td></tr><tr><td>Domain3</td><td>527</td></tr><tr><td>Domain4</td><td>2</td></tr><tr><td>Domain5</td><td>2</td></tr></table></div><br/>]]></ac:plain-text-body></ac:structured-macro>",
"representation": "storage"
}
}
}'

The error from dev console is 


I could insert an html manually by using HTML Macro but not through the REST API.

Thanks in advance
