Disconnected from the server but locally working without problems or errors

[Andrés Gil Calín]

Hi guys,

I've just deployed my first app, which works perfectly locally. Some parts work ok, but the biggest one, which involves a leaflet map, a dygraph graph and 3 selection boxes, seems to be stucked and it is not working. When i try to interact with one of this elements, the app disconnects from the server. I've already tried to make some tuning and scaling changes, but nothing. And the log does not show any error.

Any help would be very appreciated.

App url: https://futurewater.shinyapps.io/infoSequiApp/

Thank you!

How large is your data sample? If it's a large data file and it only loads when you access that portion of the app, you may be exceeding your memory limit when the app tries to load the data.

I think is not about the data. I've just discovered how to check my javascript console, and the only error i can see is this one:

htmlwidgets.js:654 Uncaught Error: All fields must be arrayswindow.

HTMLWidgets.dataframeToD3 @ htmlwidgets.js:654

(anonymous function) @ leaflet.js:852

(anonymous function) @ leaflet.js:723

addLayers @ leaflet.js:734

methods.addPolygons @ leaflet.js:849

(anonymous function) @ leaflet.js:1638

_sendMessagesToHandlers @ shinyapp.js:409

(anonymous function) @ shinyapp.js:494

_sendMessagesToHandlers @ shinyapp.js:409

dispatchMessage @ shinyapp.js:393

c.onmessage @ shinyapp.js:91

Total data is about 10 Mb, but the app doesn't uses the whole data each interaction, just a little part.

Any idea about this error?

Problem solved guys, thank you! It was one of my functions, but i didn't knew hoy to see errors on the javascript console.

I am also getting the same error. I have successfully deployed my app to shinyapps.

Application successfully deployed to https://alaka10.shinyapps.io/swiftkey/

Deployment completed: https://alaka10.shinyapps.io/swiftkey/

In the logs on shipnyapp.io I see that the package tm can not be installed.

but I can install it locally. I do not know how to fix this error.

Thanks

You cannot have an install.packages command in your application.

http://docs.rstudio.com/shinyapps.io/getting-started.html#using-your-r-packages-in-the-cloud

[Tareef Kawaf]

It sounds like you may have an install.packages() call in your application.  You should ONLY have library() calls in your application.  the deploy process will detect the dependencies and automatically install them. If that isn't the case please let us know.
