Error in building MetaGraph from DataFrames.

[niccolo99mandelli]

Hi, I'm working on the spatial-input branch and I've added some features related to reading and translating DataFrames in MetaGraph. Specifically, I've created some nearly identical function in Start.jl for initiating the simulation, in J_Space.jl for loading DataFrames and in DataFrameGraphBridge.jl for building the MetaGraph. To generate the MetaGraph, I'm using the function metagraph_from_dataframe_JHistint and passing the following parameters:
G_meta = DataFrameGraphBridge.metagraph_from_dataframe_JHistint(MetaGraph, df_edges, :origin, :destination, :weight, :weight, df_labels, :label).
Here, df_edges is a DataFrame containing information about the edges (:origin, :destination, :weight), and df_labels is a DataFrame containing information about the vertices (:label, :position, :color).
In the metagraph_from_dataframe_JHistint function, I have removed the following part because the input DataFrame (df_edges) does not have the columns defined as :Child, :Time, Subpop_Child :

    #add times on graph
    times_df = df[:,[:Child, :Time]]
    vertex_names = leftjoin(vertex_names, times_df, on = :name => :Child)
    #add subpop_child on graph
    subpop_df = df[:,[:Child, :Subpop_Child]]
    vertex_names = leftjoin(vertex_names, subpop_df, on = :name => :Child)
    # Set vertex names and attributes
    attr_names = propertynames(vertex_names[!, Not(:vertex_id)])
    for r in eachrow(vertex_names)
        set_props!(mg, r[:vertex_id], Dict([a => r[a] for a in attr_names]))
    end

I'm not sure if it's related to this change or to the function's structure itself, but when I try to launch the simulation, I encounter the following error in the third step during RUN DYNAMIC:

What could be the issue?
Thank you in advance.
