11151117
1116Send this full message to your administrator. It lists the changes they can make. The message means Claude Code refused your prompt. While you use your claude.ai login, Claude Code keeps refusing prompts, after a restart too:
1118These messages mean Claude Code refused your request and didn't send your claude.ai login:

11181120```text theme={null}
1119Claude Code didn't send your claude.ai login, because the API key helper your administrator set isn't in effect. Your organization's managed settings may be overriding it. Ask your administrator to keep the key helper and its API address in effect, to name Anthropic's API address in those managed settings, or to remove the key helper. Run /status to see your setting sources.
1121Your organization's settings need an update. Ask your administrator to fix the API key helper configuration.
1122Couldn't load your organization's settings. Check your connection, then restart Claude Code.
1123Restart Claude Code to finish signing in.

11221126**What to do:**
11231127
1124* To tell your administrator which managed sources your machine has, run `/status` at the Claude Code prompt and copy the [`Setting sources` line](https://code.claude.com/docs/en/managed-settings#read-the-source-in-/status). If a `Skipped sources` line appears, copy it too
1125* If you administer the settings, see [why the machine's key helper isn't in effect](https://code.claude.com/docs/en/server-managed-settings.md#machine-apikeyhelper-not-in-effect)
1128* `Your organization's settings need an update`: ask your administrator to fix the API key helper configuration
1129 * To tell your administrator which managed sources your machine has, run `/status` at the Claude Code prompt and copy the [`Setting sources` line](https://code.claude.com/docs/en/managed-settings#read-the-source-in-/status). If a `Skipped sources` line appears, copy it too
1130 * If you administer the settings and the helper is in a machine's managed settings file or MDM policy, see [When a machine's `apiKeyHelper` isn't in effect](https://code.claude.com/docs/en/server-managed-settings#machine-apikeyhelper-not-in-effect)
1131* `Couldn't load your organization's settings`: check your connection, then restart Claude Code. If the message comes back after a restart, tell your administrator
1132* `Restart Claude Code to finish signing in`: restart Claude Code

11271136### Invalid request header value
11281137
11291138A value Claude Code was about to send as a request header contains a character that HTTP headers can't carry: a line break, a NUL byte, or a character above `U+00FF`, such as a curly quote or a zero-width space. Claude Code stops the request before anything is sent and names the variable or setting to fix. The usual cause is a credential pasted from a document or chat that carried an invisible character or a stray line break.

2503* If the message asks you to convert the image, convert it to PNG, JPEG, GIF, or WebP and attach it again. Claude Code can verify dimensions for these formats from the file header, without decoding the image.
2504* If the message reports a dimension or size limit, resize or recompress the image below that limit before attaching.
2505* If the message names a cause, such as a CMYK JPEG, an animated WebP, or a possibly damaged file, re-save the image in the format the message sugge
2512* If the message as
