DF8105: Devframe Already Mounted

Devframe "{name}" (id "{id}") is already mounted on this hub

Message

Devframe "{name}" (id "{id}") is already mounted on this hub

Cause

ctx.install(def) was called with a devframe whose id already belongs to another devframe mounted on the same hub. Devframes are deduplicated by id, and the definition's duplicationStrategy is 'warn' (the default) or 'throw'.

Fix

Set duplicationStrategy on the definition to choose how duplicates are handled:

  • 'warn' (default) — keep the first registration, drop the later one, and emit this warning.
  • 'silent' — drop the later one without warning.
  • 'throw' — surface duplicates as a thrown error.
  • 'duplicate' — let every instance coexist under a disambiguated dock id (my-tool, my-tool-2, …).

Otherwise, remove the redundant ctx.install call (or the duplicate devframes entry) so each devframe is mounted once.

DF8104: Nested Dock Groups Unsupported

Dock group "{id}" cannot itself belong to a group (nested groups are unsupported)

DF8106: Connection Meta Not Served

The host cannot serve the RPC connection meta for devframe "{name}" (id "{id}") at "{base}" — its DevframeHost does not implement mountConnectionMeta.
