24I am using FetchXML queries with the Web API in Power Pages to retrieve data with multiple
link-entity elements. According to the documentation, FetchXML supports up to 10 link-entity elements. However, when I include more than 1 link-entity in my FetchXML query, I receive a "Web API is not available" or similar error. The query works fine with a single link-entity, but adding more causes it to fail.var fetchXml = `<fetch count="10" page="1" returntotalrecordcount="true">
<entity name="primary_entity">
<attribute name="recordid" />
<link-entity name="related_entity_1" from="id" to="related_id_1" alias="alias1" link-type="outer">
<attribute name="field1" />
</link-entity>
<link-entity name="related_entity_2" from="id" to="related_id_2" alias="alias2" link-type="outer">
<attribute name="field2" />
</link-entity>
</entity>
</fetch>`;
$.ajax({
type: "GET",
url: "/_api/primary_entities?fetchXml=" + encodeURIComponent(fetchXml),
success: function (res) {
console.log(res);
},
error: function (xhr) {
console.error(xhr.responseText);
}
});Here it works for when use one link-entity but for two it states web api is not available.
Is there a specific limitation when using multiple link-entity elements in FetchXML through the Web API?
