rbw login: failed to log in to bitwarden instance: failed to parse JSON: EOF while parsing a value at line 1 column 0

I've tried rotating encryption keys, adding backslash at the end of the paths, forcing ipv4, but no luck.

my laptop: arch linux rbw 1.8.3

philip@T430-1 ~ $ rbw config show { "email": "xxx@xxxx.xxx", "base_url": "https://api.bitwarden.eu", "identity_url": "https://identity.bitwarden.eu", "notifications_url": "https://notifications.bitwarden.eu", "lock_timeout": 3600, "sync_interval": 3600, "pinentry": "pinentry", "client_cert_path": null }

Just noting this is probably related to (or a duplicate of) #145 or #32

I think I have found the culprit for this. Looking insidesrc/config you can find a section defining the default base_url and how to format a custom one:

    pub fn base_url(&self) -> String {
        self.base_url.clone().map_or_else(
            || "https://api.bitwarden.com".to_string(),
            |url| format!("{}/api", url.trim_end_matches('/')),
        )
    }

When Bitwarden introduced the EU servers they used the same style of URL as the US one: https://api.bitwarden.eu. But the code added on an /api at the end for all "custom" URL:s, which doesn't work the official instance. Understandable, of course, since the EU servers probably didn't exist when this code was original written

Adding something like this will solve the issue:

-            |url| format!("{}/api", url.trim_end_matches('/')),
+            |url| {
+                let clean_url = format!("{}", url.trim_end_matches('/'));
+                if clean_url == "https://api.bitwarden.eu" {
+                    return clean_url
+                } else {
+                    format!("{}/api", clean_url)
+                }
+            },

I can write a PR for this when I'm back from traveling on Monday. :+1:

Any status on this?

Any status on this?

Sorry, it took a while.

Feel free to try the solution provided in #152.

You can run the agent standalone with more debugging like this: RUST_LOG=trace ./target/release/rbw-agent --no-daemonize

I can conform it worked

[Philip-Wittamore]

Confirmed fixed in rbw-1.9.0-1 arch package. Thanks!

[jurgenmehja]

Having the same issue with the latest arch package, is there a way to debug it? Using the default config btw. Thanks!

When I do rbw register it does not complain, but whenever I do rbw login|ls|get it returns the following error:

rbw login: failed to log in to bitwarden instance: failed to parse JSON: EOF while parsing a value at line 1 column 0
$ rbw --version
rbw 1.9.0
