Problem reading shapefile in shinyapps.io

[moacir]

Hi experts,

This very minimal application runs fine locally, but fails when deployed to shinyapps.io,
with "Error: An error has occurred. Check your logs or contact the app author for clarification".

The deployed application is in:
https://moacirpedroso.shinyapps.io/tst_shp/

The source appplication and data are in github:

GitHub - moacirpedroso/reprex-sf-shinyapps: Reprex to show issue when...

The actual application needs "runtime: shiny". It is included
in the example because without it I was not able to publish to
shinyapps.io.

Please, I need your help to understand what I'm doing wrong.

Thanks,

Moacir.

This is the application and the log from shinyapps.io:

I would make sure the file is indeed in/srv/connect/apps/tst_shp/br/BRUFE250GC_SIR.shp and that at least
/srv/connect/apps/tst_shp/br/BRUFE250GC_SIR.shx and /srv/connect/apps/tst_shp/br/BRUFE250GC_SIR.dbf are also there. You might also need a .prj.

Maybe you could list.files() in /srv/connect/apps/tst_shp/br/ to debug.

Hi, @etiennebr, thanks for the answer.

Yes, locally I've doubled checked that all four files( .prj, .shp, ,dbf, and .shx) are in the directory.
To deploy an app to shinyapps.io, I only have to click the "Publish" button and make sure that all
needed files are selected. RStudio does the deploying and I don´t have access to the directory
structure in their server. Besides, it runs fine locally.

[nirgrahamuk]

did you make sure all needed files are selected ?
rsconnect wont guess you need the other files as they are not named in your code

[moacir]

Well, thanks, @nirgrahamuk , I was pretty sure I had checked it, but... I'll re-publish it and post what happens this time. Thanks.

[moacir]

@nirgrahamuk, I just made shure all needed files were included, as can be seen in the attached picture, but I got the same error. If you have any other suggestion, I would be glad to hear. Thanks

[nirgrahamuk]

This doesn't necessarily show the same error. Would be better to paste us the text of the actual new log please

[moacir]

Although the reprex has another error, I managed to make the actual application work with the recommendations of @nirgrahamuk. Thanks!
