+## Troubleshooting "Failed to get profile credentials"
+
+If you receive the following error and are using AWS IAM Identity Center (previously AWS SSO), you may be missing the [`credential_process` workaround](/[platform]/start/getting-started/installation/#manually-configure-the-amplify-cli)
+
+```console
+🛑 Failed to get profile credentials
+Cannot read properties of undefined (reading 'accessKeyId')

+
+### "Unexpected token A in JSON at position 0"
+
+If you receive this error and are using AWS IAM Identity Center (previously AWS SSO), this error can be caused by selecting the `sso-session` entry when prompted for an AWS profile in Amplify CLI workflows. If this occurs, re-run the previous command and select the associated SSO profile.
