Can't login with Google account (Kiro Pro+ subscription) - "profileArn is required but no profiles are available" after successful login

[syedair]

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macOS 26.4.0 (25E246)

Expected behaviour

• After logging in with Google Sign-in, the CLI should properly load my Kiro Pro+ subscription and associated profile (profileArn).
• I should be able to send messages without any profile-related errors.
• The /model command should display all available models.

Actual behaviour

• I can successfully log in using Google Sign-in with the email tied to my Kiro Pro+ subscription.
  After login, sending any message (e.g. "hi") fails with this error:

Kiro is having trouble responding right now:
   0: Failed to send the request: An unknown error occurred: profileArn is required but no profiles are available. Please log in and select a profile.
   1: An unknown error occurred: profileArn is required but no profiles are available. Please log in and select a profile.
Location:
   crates/chat-cli/src/cli/chat/mod.rs:1647

• Running /model only shows:

Select model (type to search):
> * auto ----- credits

• No actual models are listed.
• Logging in with Builder ID works, but my Pro+ subscription (tied to Google email) is not recognized.
• This was working correctly before.

Steps to reproduce

• Open Kiro-CLI.
• Log in using Google Sign-in (with the Google account that has active Kiro Pro+ subscription).
• Once logged in, send a simple message like hi.
• Observe the profileArn is required but no profiles are available error.
• Run the command /model and notice only "auto ----- credits" is shown.

Technical Investigation

Investigated the client-side state to help narrow down the root cause.

Root Cause Found

The kiro-cli wrapper binary writes the profile with camelCase field names ("profileName") but the kiro-cli-chat binary deserializes it expecting snake_case ("profile_name"), causing deserialization to fail silently.

The debug log (enabled via KIRO_LOG_LEVEL=debug KIRO_CHAT_LOG_FILE=/tmp/debug.log) shows:

ERROR chat_cli::api_client: 350: Failed to get auth profile: missing field `profile_name` at line 1 column 114
INFO  chat_cli::api_client: 194: profileArn missing, attempting lazy resolution via list_available_profiles

The profile stored in the database (api.codewhisperer.profile key in the state table) looks like:

{"arn":"...","profileName":"Social_Default_Profile"}

But AuthProfile in crates/chat-cli/src/database/mod.rs:86-90 expects profile_name (snake_case):

#[derive(Clone, Debug, Deserialize, Serialize)]
pub struct AuthProfile {
    pub arn: String,
    pub profile_name: String,
}

Verification

1. When running the chat binary directly (kiro-cli-chat chat --no-interactive "hi") after manually fixing the JSON to use "profile_name" — chat works perfectly
2. When running through the kiro-cli wrapper — it overwrites the profile back to "profileName" (camelCase) on every launch, then the chat binary fails to parse it

Fix

Either:

• Add #[serde(alias = "profileName")] to the profile_name field in AuthProfile
• Or fix the wrapper (q_cli / fig_auth crate) to write "profile_name" (snake_case)

Workaround

Until this is fixed, users can work around it by running the chat binary directly:

kiro-cli-chat chat "your message here"

This bypasses the wrapper that overwrites the profile with the wrong field name.
