Hi Pavithra,
You can get around this by changing line 113 of the
<AM_HOME>/repository/resources/api_templates/velocity_template.xml file to
the following
<loadbalance algorithm="$!endpoint_config.get("algoCombo")">
No restart needed, just re-publish the API.
This will be fixed in the next build.
Thanks,
NuwanD.
