Server error when POSTing new annotations via REST API

[rjcommanddfo]

I'm trying to add new single-keyframe, whole-frame annotations to an existing video using the API to speed up an annotation task, but I'm getting back a "Status 500 - Server Error" message.

Here's an example of how I'm formatting my request (in R):

# Set the URL
url <- "https://biigle.de/api/v1/videos/123456/annotations"  # made up video_id

# Define annotation parameters
body_list <- list(shape_id = 7,        # whole-frame annotation
                  label_id = 194483,   # id of desired label
                  frames = 109.7688,   # desired frame
                  points = numeric())  # empty vector of points to satisfy the parameter requirement, although omitting this doesn't change the error message

# Post
res <- POST(url,
            config = authenticate(login, pass),  # stored elsewhere
            body = body_list,
            encode = "json")

# See the message
cat(content(res, as = "text", encoding = "UTF-8"))

Looking at the message shows the server error.

{
    "message": "Server Error"
}

Does this mean that there is something wrong with my request to the server, or is this an error on the server's end? Any help would be greatly appreciated - I'm fairly new to working with APIs, so please forgive me if I'm missing something obvious here!

I saw that 😉 Your request is incorrect but the validation logic of the server had a bug, too (#606).

frames must be an array (with a single element) even if it is a WholeFrame annotation.

Ah perfect that worked, thank you!!

You also found another validation bug (by sending something like points: [null]) 😃 I'll fix that, too.

Interesting! I did trypoints = array() to send an empty array for points haha
