ome-tiff examples failing with "Promise.allSettled is not a function"

[jkh1]

Describe the bug The ome_tiff_remote.Rmd and ome_tiff_local.Rmd fail to load the image, the loading indicators in all panels keep spinning, except for the Status panel which reports "Promise.allSettled is not a function".

Not sure if related to #65 since in this case there seems to be an error message.

To Reproduce Steps to reproduce the behavior:

• Install vitessceR with devtools::install_github("vitessce/vitessceR")
• Run ome_tiff_remote.Rmd or ome_tiff_local.Rmd (with path to suitable local image) in RStudio

Expected behavior Widget should display the image

Environment:

• Release or git hash: 5e76c31
• Operating system: Ubuntu 20.04
• R version: 4.2.1, all packages updated to the latest version available
• RStudio version: 2022.07.1 Build 554

The web console shows the following error before the message "Promise.allSettled is not a function" (which seems to be a warning): Failed to load resource: the server responded with a status of 404 (Not Found) and this is associated with lib/vitessceR-0.99.1/index.css

I can't find any file named index.css in the package installed by devtools::install_github("vitessce/vitessceR"). However, adding it makes the error message about it go away but still no image, only the spinners and no error message.

The warning "Promise.allSettled is not a function" comes from index.js line 1344 which seems to be implementing a shader so might be related to rendering of the image.

This is because the rstudio viewer pane is using an old version of JavaScript. The promise.allsettled API is supported in every major web browser https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/allSettled#browser_compatibility I will try adding a polyfill for Promise.allSettled but if it does not work I can try adding a warning message in the console to explain when the viewer_pane query parameter is detected https://search.r-project.org/CRAN/refmans/rstudioapi/html/viewer.html In the meantime, you can try clicking the "Show in new window" button to run in a standalone web browser.

you can try clicking the "Show in new window" button to run in a standalone web browser.

This is what I did and how I could get to the web console. In the meantime, running it as a shiny app also fails with no error message with a warning for the same line of index.js (1344) but with a different message: "GeoTIFF source is missing offsets proxy."

With the mention of offset, could this be related to this avivator issue hms-dbmi/viv#634 where it failed when it couldn't find an offset.json file?
