I have a script that runs fine as a toolbox script in Desktop Pro, however when I try to run the same script in ArcGIS Online as a notebook, I get the following error:

TypeError: float() argument must be a string or a number, not 'dict'

For this line of code:

 

    new_feature_layer = sdf.spatial.to_featurelayer(
        title=f"Polys Centroids {tmp_uuid}",
        gis=gis,
        tags=["centroids", "outputs"],
        folder=TMP_FOLDER,
        sanitize_columns=False,
        service_name=f"polys_centroids_{tmp_uuid}",
    )

 

Here's the full stack trace for the error:

And this is the surrounding code in the method where the error occurs:

 

def generate_points(_args):
    gis = _args.gis
    poly_feature_layer = gis.content.get("7da90f1a777c4d6e9d59e3314e70fbe5")
    print(poly_feature_layer["url"])
    poly_feature_layer2 = FeatureLayer(poly_feature_layer["url"] + "/0")
    # EPSG 4326 is a coordinate system for lat/long that makes used of the WGS84
    # spheroid
    sr = 4326
    df = poly_feature_layer2.query(
        as_df=True, return_centroid=True, return_geometry=False, out_sr=sr
    )
    print("Here 61")
    print(df.iloc[0])
    # Convert centroid to dict
    sdf = GeoAccessor.from_xy(
        df.join(pd.DataFrame(df.loc[:, "centroid"].to_dict()).T),
        "x",
        "y",
        sr=sr,
    )
    print("Here 62")
    print(sdf.iloc[0])
    sdf = sdf.drop("Correct_Area_SqM", axis=1)
    print("Here 63")
    print(sdf.iloc[0])
    # Create a shortened uuid to avoid name clashes.
    # We made want to add cleanup for all temporary layers.
    tmp_uuid = "".join(
        random.choice(string.ascii_letters + string.digits) for _ in range(6)
    )
    print(tmp_uuid)
    new_feature_layer = sdf.spatial.to_featurelayer(
        title=f"Polys Centroids {tmp_uuid}",
        gis=gis,
        tags=["centroids", "outputs"],
        folder=TMP_FOLDER,
        sanitize_columns=False,
        service_name=f"polys_centroids_{tmp_uuid}",
    )
    return new_feature_layer

Update - I was able to get this issue (and some others that were also related) resolved by switching from the Standard to the Advanced runtime.

Donald, you would be better off filing an issue with Tech Support, or better still, file one on the arcgis github site
