Today, after upgrading versions, OH can't connect to agent-server caused by this pydantic validation error:
```agent_definitions.3.mcp_config.tavily.env.TAVILY_API_KEY
  Input should be a valid string [type=string_type, input_value=SecretStr('**********'), input_type=SecretStr]```
Any hint?

I solved the issue by removing these 2 configs in `meta.json`:
```agent_definitions > mcp_config
agent_definitions > mcp_servers```

```cd /workspace/conversations/SESSION/
mv meta.json meta.json.bak
jq '.agent_definitions |= map(del(.mcp_config, .mcp_servers))' meta.json.bak &gt; meta.json```

Arghh...after restarting the conversation, `meta.json` was recreated and now there is another error:
```pydantic_core._pydantic_core.ValidationError: 1 validation error for Event

parent_id
  Extra inputs are not permitted [type=extra_forbidden, input_value='f2a79c4a-0a1b-4ed2-850c-170bc560ad0e']```
