Troubleshooting

Common issues when integrating the Web SDK v2, and how to resolve them.

The avatar doesn't appear

The container element likely has no size. The avatar fills its wrapper, so a 0 × 0 wrapper renders nothing.

<div id="AIPlayerWrapper" style="width: 480px; height: 720px;"></div>

Also confirm init() resolved successfully — it rejects if the AI failed to load.

The avatar appears but there's no sound

Browsers block audio until the user interacts with the page.

warning

Trigger the first send() from a user action (a click or tap). Calling send() on page load renders the avatar but stays silent.

button.onclick = () => AI_PLAYER.send("Hello!");

generateToken fails

Symptom	Likely cause	Fix
status is not "success"	ClientToken is invalid or expired	Re‑issue the ClientToken on your server and call generateToken() again
Rejected immediately	Wrong appId, or appId/token mismatch	Ensure the appId matches the one used to mint the ClientToken

danger

Never generate the ClientToken in the browser — it requires your userKey, a long‑lived secret. Mint it on your server and pass only the short‑lived ClientToken to the client.

"Avatar not found" on init

• Verify the aiName exists in the list returned by AI_PLAYER.getAIList().
• Confirm your account has access to that avatar.

Speech starts but stops or stutters

• Check the browser console for network errors and confirm a stable connection.
• Listen for onAIPlayerErrorV2 and inspect the error code/message.

Nothing works and the console shows errors

Add the error/log hooks and share the output with support:

AI_PLAYER.onAIPlayerErrorV2 = (err) => console.error(err?.code, err?.message);

Still stuck? Contact DeepBrain AI support with the console output and your aiName.
