09/04/2025, 9:36 AMthings were working great last night, 12 hours ago. today it's a disaster - agent makes tool calls using ghl integration but stops responding until user speaks again. about 50% of the tool calls get response 'null' even when the user exists in the CRM
n8n tool call is made but agent stops talking

09/04/2025, 9:37 AMThanks for sharing the details and call IDs. To help narrow down the issue, could you let me know if there were any changes to your n8n webhook or GHL integration setup in the last 12 hours before the problem started? Even a small update or configuration change could be relevant.
This will help determine if the "null" responses and agent silence are related to a recent change or an intermittent platform issue.

09/04/2025, 9:37 AMThanks for sharing the call IDs and details. To help narrow down the issue, could you confirm if you have made any recent changes to your n8n webhook or GHL integration settings before these failures started occurring? Even small configuration updates can sometimes cause unexpected behavior.
Example:
- Updated webhook URLs
- Changed authentication or permissions
- Modified integration logic
This will help determine if the problem is related to a recent change or something else.

09/04/2025, 9:38 AMno it was working last night, i demo'd for a youtube video and it was working. today no change. you can see the logs that the response is received, in both ghl and n8n webhooks. but the agent stops talking.

09/04/2025, 9:38 AMthe first order of operations is that the agent stops speaking after the request is sent

09/04/2025, 9:39 AMeven when the response comes back with correct information

09/04/2025, 9:39 AMsecond issue is that some of the tool calls come back with 'null' data, particularly the ghl request to the CRM get_contact

09/04/2025, 9:39 AMit calls get_contact and it comes back 'null' even when the user exists. this happens erratically

09/04/2025, 9:40 AMthere has been no change to settings from last night

09/04/2025, 9:42 AMi see my title is incorrect, as i checked the log and it did in fact make the n8n tool call. it did not show up in the chat as usual during the call so i thought it failed. the issue is that the agent goes silent after the tool call until the user speaks
