Hello - I’m trying to figure out why a plot I’m passing to the `components()` method is failing to return the key:value pairs { “modelid” : something } and { “elementid” : something } within the ` ``` But these did not seem to have an effect on the outcome. I’ve been attempting to follow an example of this implementation I found here: [Interactive Realtime Visualiation with Bokeh+Flask](https://betterprogramming.pub/deploy-interactive-real-time-data-visualizations-on-flask-with-bokeh-311239273838) The main difference between how the example does it and I’m trying to do it is how the `source.data` attribute is being populated. In their case, they pull in a CSV from a website called “[easybase.io](http://easybase.io)”. I can’t do that due to the sensitivity of my data, so instead I’m just flattening the returned dataframe `report_df` with a `.to_list()` call. This blog describes `js_resources()` and `css_resources()` as “general Bokeh-required JavaScript” and “General Bokeh-required CSS”, respectively; but it did a poor job explaining how the `INLINE` call to these methods works. I suspect that this is the root cause of my problem, given that all my variables seem to be populating correctly. I’ve checked and double checked my dependancies. I don’t think those are causing the issue. I’ve been referencing documentation for v.2.3.1 and have that version installed. I’ve done pretty extensive testing to ensure that the dataframe being passed to `source` (which you see when I’m constructing the plot in my `BokehObject`) is filling out properly. I’ve also found that within the source attribute `source.data`, the “x” and “y” I define there seem to be correct. When I run my flask application, I get the following: ![Bokeh Flask App Screenshot](https://discourse-uploads.bokeh.org/original/2X/6/6499698d9dcd2ad91c4fcaacd61c920a037f95dc.png) So, the plot appears to be constructing, but the data is not being passed, or isn’t plotting, or something. Why do I not see modelid or elementid in the `
