Error for read_camtrap_dp on example camtrapDP dataset

[LisaNicvert]

Hello! I am trying to use camtrapDP for a package I am creating. When I try to read the camtrapDP example dataset (from https://github.com/tdwg/camtrap-dp/tree/1.0-rc.1/example), I get the following error:

> dat <- camtraptor::read_camtrap_dp("https://raw.githubusercontent.com/tdwg/camtrap-dp/1.0-rc.1/example/datapackage.json")
Please make sure you have the right to access data from this Data Package for your intended use.

✖ Column `cameraSetup` doesn't exist.
Run `rlang::last_trace()` to see where the error occurred.

Here is the output of rlang::last_trace:

It used to work in the past, but it seems to be broken (maybe because I updated my version of R (4.1.xx -> 4.3.0) or maybe because the example dataset changed since I last tried).

Below is my session info:

Do you know what is going on? Thanks!

Hi Lisa! Thanks for reaching us.

The problem is that the example dataset changed, indeed. As you see, the version mentioned in the link is "v1.0-rc.1".

We are working on allowing camtraptor to read cameratrap datapackages written following version 1.0-rc.1, where rc-1 stays for release candidate number 1. Up to now, camtraptor supports data using camtrap-dp format version 0.1.6. If you are using Agouti, notice that the legacy Agouti exports are not yet written following version 1.0-rc.1.

We are tackling this issue (#196) in PR #223 (still a draft, work in progress). It will be solved asap (= very likely next few days, for sure in July).

I hope I could clearly answer to your question.

[LisaNicvert]

Thank you for your answer, it's clearer now. I noticed the issue #196 you linked in your answer, but I was unsure this was linked to my problem. Sorry for the duplicate!

[damianooldoni]

No worries! 👍
