Shows error Cannot connect to cyclotron-svc (getTopDashboards)

Hi @rahbal, did you configure the _public/js/conf/configService.js file after building the website? It gets generated on first build from sample.configService.js, and contains this by default:

restServiceUrl: 'http://localhost:8077',

From what you said, that's probably correct, but if you changed it you might run into errors.

If that's not the issue, did you correctly start MongoDB and connect the service to it? You can test this via http://localhost:8077/dashboards. It should have deployed some example dashboards automatically on startup, so you should get some JSON response. If there are any errors, it's likely that the website is connecting correctly, but is unable to get a valid response.

Lastly, you can open the browser console and look for any more detailed errors when you load the site.

Yes, all dashboards are visible on this url http://localhost:8077/dashboards

Only cyclotron-site is showing that it is not able to connect to the cyclotron-svc.

Any luck finding errors in the browser developer console?

I bumped into what looks like the same issue:

[karel1980]

I started by running cyclontron-svc using the sample.config.js; settings analytics enabled = true in that file gets rid of the 405, but now I get a 500. The error on the console of cyclontron-svc says Error [MongoError]: The 'cursor' option is required, except for aggregate with the explain argument. I haven't investigated yet, pretty sure that's a configuration error on my behalf

[karel1980]

upgrading mongoose to 6.2.10 seems to make the error go away; fyi I'm running mongo 4.4, that's probably relevant

[karel1980]

I'll create a PR; I find any tests in cyclotron-svc, though I have to admit I didn't look very hard.

[karel1980]

Since there is an open PR for bumping mongoose that's 3 years old [0] I don't think this project is being maintained very actively anymore.
