            Can't collect price from a webpage using vba/selenium in headless mode
            Asked 2021-Jun-14 at 22:25

            I've created a vba script in combination with selenium to scrape price $8.97 from this webpage. The script does fetch the content if I run it in non-headless mode. However, my intention is to grab the content in headless mode. I know I can use their api to fetch the price but the very api gets blocked after 4/5 requests, so I intentionally chose this route.

            The service account providing authorization to Terraform is missing the permission resourcemanager.projects.getIamPolicy which is the source of the error message.

            The service account is also missing the permission resourcemanager.projects.setIamPolicy which is required to change IAM policies.

            Those permissions are part of the role roles/resourcemanager.projectIamAdmin (Project IAM Admin).

            What version of terra are you using? I ask because I believe that the current version will give a warning but proceed. Also, you could of course aggregate with 100 instead of 113 so that the origins are not changed.

            They easiest approach may be to make a virtual raster like this:

            v <- vrt(files, "my.vrt")

            and then proceed with

            r <- rast("my.vrt")

            and perhaps

            a <- aggregate(r, 100)

            Or whatever it is you would like to do.

            This is but tricky to debug because you mix different packages, and you do not show(object). Anyway, here is a terra approach, showing where it would be useful to see the objects metadata; and a plot that shows the raster and vector data together.

            Why is terra package dropping these values when using extract function?
            Asked 2021-May-09 at 02:45

            I use terra package to extract pesticide application from raster files. In the extract step it seems that terra removes some rows. In this example there are 19 warnings where it says:

            Failed to compute min/max, no valid pixels found in sampling. (GDAL error 1)

            After the extract step I have fewer rows left and it seem to have dropped some rows.

            This step worked fine using raster (from here Using raster to calculate the mean application and total application of pesticides, but numbers not adding up) but it is unfortunately to slow given the amount of files I need to process.

            Any ideas what this error means and how to solve it?

            This happens because some of the polygons are so small that they do not cover a raster cell. This has now been fixed in the development version (terra >= 1.2.8); but here is an alternative approach with the exactrextractr package --- this is fast and gets you a very precise estimate, which is especially relevant when your raster cells are relatively large as in this case (although wrld_simpl is rather imprecise).

            A SpatRaster cannot be serialized, you cannot send it to parallel compute nodes. Have a look here for more discussion.

            Instead you can (a) send and receive filenames; (b) parallelize your custom function that you supply to app or lapp; (c) use the cores=n argument (where available, e.g. app and predict); (d) use a mechanism like wrap; (e) send a filename and a vector to make a SpatExtent to process and create a virtual raster from the output tiles (see ?vrt).

            For example, you could do use a function like this (Option "a")
