opentui: fatal: undefined is not an object (evaluating 'enabledFormatters().length') after adding an MCP

[alepouna]

Description

After I added an MCP server to a local project config file /project-root/opencode.json and running /status this error pops up

opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "directus": {
      "enabled": true,
      "type": "remote",
      "url": "https://server.domain/mcp",
      "headers": {
          "Authorization": "Bearer token"
      }
    },
  },
}

TypeError: undefined is not an object (evaluating 'enabledFormatters().length')

This issue might be a duplicate of existing issues. Please check:

• opentui: fatal: undefined is not an object (evaluating 'enabledFormatters().length') #8042: opentui: fatal: undefined is not an object (evaluating 'enabledFormatters().length')
• opentui: fatal: undefined is not an object (evaluating 'enabledFormatters().length') #4922: opentui: fatal: undefined is not an object (evaluating 'enabledFormatters().length')

Both issues report the exact same error with the same stack trace. Feel free to ignore if your specific case differs from these.

Will iinvestigate, I think there is some timing issue w/ the tui and instances being disposed...

Closing as duplicate of #4922 - same enabledFormatters().length undefined error.
