Execution Data

Read details about the current run, or tag the run with a value you can search for later in run history.

What it does

Execution Data has two operations, chosen with Operation:

• Read run context outputs this run’s id, the workflow id, how the run was started (the trigger type), when it started and how long it has been running.
• Attach metadata saves a Key and Value pair on the run. Run history shows the pair on the run’s row and in its detail panel, and the history search box finds runs by either half of a pair, by run id or by status. Tag a run with order = 4471 and searching “4471” brings it back.

Values are always stored as text, so numbers and true/false stay searchable. You can attach several pairs by using the node more than once.

When to use it

• Make runs findable by something meaningful, such as an order number, a customer or a page, instead of only by time.
• Branch on how a run started, for example handle a scheduled run differently from a manual one.
• Put the run id or elapsed time in a log line or a message.

To remember values from one run to the next, use Data Store instead.

Inputs and settings

Réglage	Type	Ce que cela fait
Operation	Choice	Read run context, or attach metadata to the run. Options: Read run context, Attach metadata. Par défaut : Read run context
Key	Text	Name of the metadata field to attach (Attach metadata only).
Value	Text	Value to store under the key (Attach metadata only).

Value is usually an expression, such as {{ $input.orderId }}. Key is required for Attach metadata.

Outputs

• Output

Read run context outputs:

Field	Meaning
runId	The id of this run, or null outside a workflow run.
workflowId	The workflow this run belongs to, or null.
triggerType	How the run started, such as schedule, manual, contextmenu or chat, or unknown.
startedAt	When the run started, as an ISO timestamp, or null.
elapsedMs	Milliseconds since the run started, or null.

Attach metadata outputs key and value (the pair just written), metadata (every pair on this run so far) and persisted, which is false when the node ran on its own and there was no run to tag.

Dependencies and credentials

None. This node needs no connection and has no slots for other nodes.

Example workflow

Tag each run with the page it processed, then find it in run history:

1. Context Menu trigger, Menu Contexts Page.
2. Execution Data, Operation Attach metadata, Key page, Value {{ $input.tabTitle }}.
3. The rest of your steps, for example Get All Text and a summary.
4. Later, open run history and type part of the page title in the search box to find that run.

Common issues

• “Attaching metadata needs a key.” Key is empty. Fill it in.
• persisted is false. You tested the node on its own. Run the whole workflow and the pair is saved on that run.
• triggerType is unknown. The trigger’s triggerType field did not reach this node, usually because a node in between replaced the data. Place Execution Data right after the trigger, or turn on an “include input fields” option in the nodes between.
• The metadata does not show in run history. Metadata is saved with runs recorded in this browser profile (local mode). Run context works in every mode.
• A paused run lost its metadata after resuming. A resumed run is recorded as a new run with its own id. Attach the metadata again after the pause.

Related nodes

• Data Store: remember values between runs.
• Switch: route by triggerType.
• Error Trigger: react when a run fails.
• Digest: collect items across runs and release them together.
