Copy failed: ${res.status}

Error message

Copy failed: ${res.status}

What it means

HTTP 404 from POST /blocks/{block_id}/execute when get_block(block_id) returns nothing — the block identifier is not registered in the running backend's block registry. The block may exist in the codebase but be unregistered (import failure, disabled provider) or the id may simply be wrong.

Solutions

1. List available blocks (GET /blocks) and use the exact id from the registry.
2. If the block should exist, check backend startup logs for import/registration errors and missing optional dependencies.
3. Regenerate frontend API types after backend upgrades so block ids stay in sync.

Example fix

// before
await api.post(`/blocks/${blockId}/execute`, data);

// after
const blocks = await api.get('/blocks');
const block = blocks.find(b => b.id === blockId);
if (!block) throw new Error(`Block ${blockId} not registered`);
await api.post(`/blocks/${block.id}/execute`, data);

const blocks = await api.get('/blocks');
if (!blocks.some(b => b.id === blockId)) throw new Error('Unknown block');
await api.post(`/blocks/${blockId}/execute`, data);

const isRegisteredBlock = (blocks: Block[], id: string): boolean =>
  blocks.some(b => b.id === id);

const resp = await api.post(`/blocks/${blockId}/execute`, data);
if (resp.status === 404) { refreshBlockRegistry(); }

When it happens

Trigger: Calling direct block execution with a block id that isn't registered: typo, a block removed/renamed between versions, or a block whose provider module failed to import so it never registered.

Common situations: Frontend built against a newer backend that has a block this backend lacks (version skew); block renamed with the old id persisted in saved state; conditional blocks that only register when their optional deps are installed.
