Error creating a customContent on a confluence addon

Question

Today I was trying to create a confluence addon for my company and I've try following atlassian documents.

My problem comes trying to run the express app when adding a new customContent to the atlassian-connect.json, after running npm start I get the following error.

Failed to register with host https‍://admin:[email protected]/wiki (200) {"type":"INSTALL","pingAfter":300,"status":{"done":true,"statusCode":200,"con tentType":"application/vnd.atl.plugins.task.install.err+json","subCode":"upm. pluginInstall.error.descriptor.not.from.marketplace","source":"https‍://1a0adc 8f.ngrok.io/atlassian-connect.json","name":"https‍://1a0adc8f.ngrok.io/atlassi an-connect.json"},"links":{"self":"/wiki/rest/plugins/1.0/pending/b88594d3-c3 c2-4760-b687-c8d860c0a377","alternate":"/wiki/rest/plugins/1.0/tasks/b88594d3 -c3c2-4760-b687-c8d860c0a377"},"timestamp":1502272147602,"userKey":"xxx","id":"xxx"}

    ]
}
}

Does anybody has an idea on whats going on?

Answer 1

The contentViewComponent can't find the generalPage it is referencing in moduleKey.

From the docs:

In the snippet above, the moduleKey “customersViewer” maps to a generalPage module we have defined in our add-on. This generalPage is passed the context parameters we specify, and visualizes our content accordingly.

If you change the generalPage with the key hello-world-page-confluence to customersVieweryou be able to install and get up and running.
