Issue with Running BrowserUse WebUI – Agent Fails to Execute Task

[vldmcr]

Hi everyone,

I’m encountering an issue while running the BrowserUse WebUI. Here’s what happens:

1. I start the application using:
   web-ui % python3 webui.py

The application runs successfully, and I get the following output:
INFO [browser_use] BrowserUse logging setup complete with level info
INFO [root] Anonymized telemetry enabled. See https://github.com/browser-use/browser-use for more information.

• Running on local URL: http://0.0.0.0:7788
• Running on public URL: https://bbec4f7c4c7285f80d.gradio.live

2. I configure the parameters in the application (see attached screenshot for details)

3. When I try to run the agent with the task:
   go to google.com and type 'OpenAI' click search and give me the first url

The agent fails to execute the task, and I get the following error in the terminal:
INFO [agent] 🚀 Starting task: go to google.com and type 'OpenAI' click search and give me the first url
INFO [src.agent.custom_agent]
📍 Step 1

when i ask Deepseek about this error:

📌 Example of Correct Configuration
Setting: Value
API Key: sk-your-new-key (51 characters) ---> My Deepseek API key and every new one I generate have with sk- 32 characters??
Base URL: https://api.deepseek.com/v1
Model Name: deepseek-chat

Could someone please help me troubleshoot this issue?

Thank you in advance!

Please make sure your Deepseek API key is correct. However, recently the Deepseek official website has been down all the time. There may be a problem with unsuccessful calls.

About Deepseek API key, it's correct, i tested it in terminal:

Additionally, after this test in the terminal, it see tokens are used in the DeepSeek API platform.

but in when i try again to use run agent from webui, it shows me:
📍 Step 1
ERROR [agent] ❌ Result failed 1/5 times:
Error code: 404 - {'error_msg': 'Not Found. Please check the configuration.'}
