st.column_config.JsonColumn

Using Streamlit
,
1

I am trying to use st.dataframe to read and display data from a table. One of the columns contains JSON data, stored as JSON in MYSQL.
I am on streamlit 1.45.0, upgrading to 1.46 requires a lot of changes for navigating between pages so avoiding it for now.

column_config = {
            "id": st.column_config.TextColumn(
                "ID",
                width="medium",
                help="Unique identifier "
            ),
            "data": st.column_config.JSONColumn(
                "Data",
                width="large",
                help="JSON data"
            )
        }
        
        st.dataframe(
            results_df,
            column_config=column_config,
            use_container_width=True,
            hide_index=True
        )

I am using a Docker container to run this, I verified that the streamlit version installed in the container is 1.45

But I am seeing the following error:

AttributeError: module 'streamlit.column_config' has no attribute 'JSONColumn'

Traceback:

    "data": st.column_config.JSONColumn(
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^

I changed versions to see if it would solve the error, but it doesn’t.
Currently defaulting to TextColumn to get around this.

It’s JsonColumn, not JSONColumn, see here – maybe that already fixes it?
