Additional context

\n

I would like to explain my method to fix the bug below.

\n

As I gradually delete the existing content in the Proxy input field in the Setting interface, the proxy option in the ~/Library/Application Support/Follow/db.json file is updated in real time.
However, when the content deleted from the Proxy field can no longer be parsed into a valid URL or becomes empty, the proxy in db.json stops updating.
Similarly, if the content in the Proxy input field in the Setting interface is directly changed to a string that cannot be parsed as a valid URL, it will not trigger an update to db.json.

\n

Therefore, it can be concluded that the function setProxyConfig handles both the empty string and invalid string inputs in the same way——not to update the db.json file.

\n

To differentiate between these two cases, I chose to modify the return value of the function normalizeProxyUri called within function setProxyConfig. Specifically, when the input is an empty string, I made the function normalizeProxyUri return an empty string. This allows the function setProxyConfig to update the proxy field in db.json to an empty string via store.set.

\n

Note: Since I haven’t set up the related environment on my computer, I hope someone else can help with building it and testing whether my method can actually resolve Issue #2786 without causing any other issues.
