Plot_ly graph not rendering in shinyapps.io

[matt_harmston]

I am new to this group, but could use some collective wisdom. I built a Shiny app that has a simple user interface, dynamic text, and a plot_ly scatterplot. It works perfectly on my local servers. When I pushed it out to shinyapps.io, everything works correctly except that the plot_ly graph won't render. The error provided is one that I programmed custom, suggesting that there's an issue with the data. However, given that the dynamic text and interface work properly, I can rule that out. What is the best way to ferret out any little-known codicils that might interfere with rendering plot_ly on shinyapps but not on my local server? Note, the log says nothing about missing packages, and I've added graphics.off() and pdf(NULL).

The broken app can be found here: https://average-score-change.shinyapps.io/change_in_average_composite_score/

Thanks,
Matt

You are not giving us much to work with, could you paste the content of your logs for that app and maybe some relevant code?

Andresrcs,

I appreciate your taking the time to respond. I'll be more conscious of code/logs going forward.

That said, in running the app and pulling up the subsequent log to share with you, this morning's log differed almost entirely from what I saw yesterday. Of particular note was a previously unseen error indicating a missing package. I am unsure how/why the logs looked different, maybe an id10t error or...? Regardless, calling windowsFont (without package support) immediately above the point at which I created the plot was the issue. I fixed the windowsFont issue, republished, and now things work properly.

If your question's been answered (even by you!), would you mind choosing a solution? It helps other people see which questions still need help, or find solutions if they have similar problems. Here’s how to do it:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …

We'll do. Thanks again.
