mapshot error: webshot.js returned failure value: 1
I have a similar Problem. I am working with R Markdown and so far I created a html report with maps. The maps were created with leaflet and then converted into a jpg with mapshot. Since the last R update mapshot(leafletmap, file.jpg) creates this error: Error in (function (url = NULL, file = "webshot.png", vwidth = 992, vheight = 744, : webshot.js returned failure value: 1
Any help is much appreciated!
I want to make my question more concrete with an reproducible example:
library("leaflet") library("rgeos") library("maptools") library("mapview")
m <- leaflet() %>% addTiles() %>% # Add default OpenStreetMap map tiles addMarkers(lng=174.768, lat=-36.852, popup="The birthplace of R") m mapshot(m, file = "C:/Users/kkueth/Rplot2.jpg", fgb = FALSE) # Hier einen passenden Speicherort suchen
(by the way: I have found a similar problem on github that is already closed without solution, but I didnt manage to reopen it)
I can only guess (as I have no problem with the example) that your webshot.js installation is somehow not correct. Have you tried re-installing webshot or at least using webshot::webshot() directly?
Thank you for your answer and the information that it works for you. Re-installing webshot or using webshot::webshot() doesn't work for me. I guess the R update saved the whole win-library on a new destination (I don't know why). I try to fix this by deleting and installing R again.
@tim-salabim I deleted R and RStudio and installed both from the beginning, but nothing changed. I have no idea what else I could try out. Do you have any suggestions?
What seems weird to me: I use R on two different servers and both show the same error. (with one of them I tried the reinstallation of R)
hm, then it might have to do with the phantom.js setup. I think, especially as you say that it also fails with webshot, this is best filed as an issue at https://github.com/wch/webshot/issues
To make it more concrete:
I work on a laptop and remote on a server (to be able to handle more data). On both (laptop and the server) R and R Studio is installed and on both it doesnt work. On the laptop I tried the reinstallation of R but this didnt help.
hm, then it might have to do with the phantom.js setup. I think, especially as you say that it also fails with webshot, this is best filed as an issue at https://github.com/wch/webshot/issues
Thank you, I will try this
I am facing the same issue as KathaRRRina.
In my case, however, webshot works properly (I have already seen the proposed solutions here https://github.com/wch/webshot/issues/112
The following reproducible example creates the .jpg through webshot but not through mapshot.

I am happy that I am not alone :)
For me it now it works exactly like for @niknikos :
webshot creates the jpg, but mapshot doesn't.
Thank you for your examples @niknikos, they helped me to find out how to create the jpg with webshot.
However, the mapshot version needs less code, so I would still be happy about a solution of the problem.
Same problem for me, webshot creates the jpg, but mapshot doesn't.

Hi all, please see https://github.com/r-spatial/mapview/issues/423#issuecomment-1146598142 Can you please install that branch and let me know if it solves the spurrious webshot error you've been experiencing?
Hi @tim-salabim ,
Thanks for the effort. I installed the suggested branch at #423 and used the example there.
library(mapview) library(stars)
#Sys.setenv("CHROMOTE_CHROME" = "/usr/bin/brave-browser") # just in case chromote cannot find a suitable browser
lc <- read_stars(system.file('tif/lc.tif',package='stars')) tst_mv = mapview(lc) tst_mv # legend there mapshot(x = tst_mv, file = paste0(getwd(),"/test.png")) # legend gone
When running R-Studio in user mode, mapshot creates the .png or .pdf image as expected. When running R-Studio in admin mode, mapshot does not create the .png or .pdf image as expected, throwing the following error message:

In my case, I need to be using R-Studio in admin mode to build my book using bookdown, so the suggested solution is not sufficient. In the past, i.e. before replying to the post here, this was not a problem. Mapshot worked properly in admin mode, too. Hope the above and the session info is helpful.

Webshot2::webshot does not work whereas webshot::webshot does.
I think it is perhaps proxy related (I have same kind of problem with pagedown and make multiple tests with cromote etc.... The problem only affects people with authenticated proxies).
@tim-salabim I'm able to write in tempfile : txtPath <- tempfile(fileext = ".txt") writeLines(text = "Hello, World!", con = txtPath) readLines(txtPath)

I am currently contemplating to have two different functions:
- mapshot - using webshot::webshot()
- mapshot2 - using webshot2::webshot()
The other option would be to introduce a switch in mapshot() and have an option which one to use by default.
Any preferences?

@niknikos thanks for these. I should have said to use the reprex with the current version of the main branch, not the feature branch. Can you rerun after
remotes::install_github("r-spatial/mapview")
?
@tim-salabim sorry about that. I have now updated my previous post with the output based on
remotes::install_github("r-spatial/mapview")
@niknikos it's my first time to try the reprex package and unfortunately it didn't work for me. Your example works fine for me until:

Sorry for this "ugly" code. I would love to find out how reprex works in future. For me mapshot creates the same error here, as before: Error in (function (url = NULL, file = "webshot.png", vwidth = 992, vheight = 744, : webshot.js returned failure value: 1
@KathaRRRina perhaps this https://teachdatascience.com/reprex/ can be of help. Particularly the Copy and paste section.
I have encountered the same problem. The problem is when you call the webshot::webshot but it cannot return the correct path style in windows system. '\' >>> '%5C'. I have no idea if you have right to fix webshot::webshot directly but.... that it. I hope this can be fixed as soon as possible.
Also having this issue and where it saves the .html file fine, it fails to takes a snapshot of the html using webshot() for the png output. This is the error I am getting (I replaced my username but it does find the correct path as I found the file myself):
Could not load c:%5CUsers%5CXXXYYYZZZ%5CAppData%5CLocal%5CTemp%5CRtmp2twFvl%5Cfile54e02ddf6a28.html
Error in (function (url = NULL, file = "webshot.png", vwidth = 992, vheight = 744, :
webshot.js returned failure value: 1
So perhaps as @EmsAlan mentioned, it might be to do with the replacement of backslashes to %5C?
EDIT: I managed to use the combination of webshot::mapshot() and webshot2:webshot() to output a png. I first save the .html file to a specified file location using mapshot and then I load it as the url in the webshot function. Bit of a workaround but at least it works for now.
