    Hi TL;DR: How to overwrite context in
    config.toml
    by context provided in prefect UI's context section while running a flow? I am facing problem with updating/overwriting context values from prefect UI. I have defined a user configuration file for the agent at
    ~/.prefect/config.toml
    with following syntax
    [context]
    postgresdb = "production"
    Now, I want to update this attribute
    postgredb
    from the UI by passing context with same name and different value like following
    {
      "postgresdb": "test"
    }
    When I obtain this context name in task, it gives me the value from
    config.toml
    not the updated value from the context provided in the UI
    print(prefect.context.get('postgresdb'))
    >>>production
    Can someone guide me through this? Please. I have read the documentation multiple times and have also gone through the prefect source code in an attempt to understand how contexts get merged but I could not understand it. From the code, it appears that whatever context is passed through
    **kwargs
    overwrites the context in the
    config.toml
    . I believe prefect UI is passing context via
    **kwargs
    only.

    Hi @Krishna Devenda i just ran a flow to see if I could reproduce this and I am unable to! My context sent from the UI updated appropriately 🤔 Could you open up this as an issue on the repo w/ an example of your flow so we can look at it there?

    Yeah sure, I will open up an issue on the repo with steps to reproduce. I noticed a strange behaviour where if there are more than one task in the flow and at least one task is getting executed before a task in which I retrieve the context, the context does not get updated but if the task in which I retrieve the context gets executed first of all, the context gets updated.
    Hi @josh, I have opened an issue on the repo. Here's the link to the issue https://github.com/PrefectHQ/prefect/issues/3956 Please have a look and thank you for your time.🙏
