HELP No running instances for module


I follow the guide ‘’, to build a single server in Linux.
When do step ’ Deploy a compatible FOLIO backend, enable for tenant’, item ‘Post the list of backend modules to deploy and enable.’, got error as below:

curl -w ‘\n’ -D - -X POST -H “Content-type: application/json” \

-d @platform-core/okapi-install.json
HTTP/1.1 100 Continue

No running instances for module mod-calendar-1.3.2. Can not invoke /_/tenant

Pls advice, thx a lot.


Hi Alen,

You might do better asking on the #support Slack channel, since developers are not here on Discuss very much. If you have not already signed up for FOLIO Slack, you can do that at


HI Ann,

Hi Alen – I’ll send you an invite email directly from Slack.
