## 1 Glossary

When you click the **+** button in an AI Table automation to reference content, you'll meet specific terms. This page explains the variables and fields you can reference.

### 1.1 AI Table variables

Click **+** in the right panel to add field variables from this AI Table — handy for sending a list of field values to someone or for writing a created group's ID back to a record.

#### 1.1.1 View URL

The URL of an AI Table view. Open the URL to land directly on that view.

### 1.2 Record variables

Usually surface when an earlier step contains a specific record and a later step references it.

#### 1.2.1 Record ID

The unique identifier of a row. Unique within a single table — but may collide across tables in the same database.

#### 1.2.2 Workflow author

The person who configured this automation.

#### 1.2.3 Workflow trigger time

Includes today (the trigger time), tomorrow (trigger time + 1 day), and day-after-tomorrow (trigger time + 2 days).

### 1.3 Attachment fields

Includes attachment size, name, type, and a temporary URL (expires 2 hours after generation).

### 1.4 Group fields

Use a group ID to send messages to that group; or write the group ID into a Group field — it'll render as a "Group card link".

## 2 Common errors

### 2.1 The table has been deleted — please reconfigure the workflow

Cause: the table was deleted.

Fix: reconfigure the automation; pick a different table.

### 2.2 The specified record does not exist

Cause: shows up in **Update record** when the target record doesn't exist.

Fix: reconfigure the automation.

### 2.3 The field has been deleted

Cause: the field was deleted.

Fix: reconfigure the automation; pick a different field.

### 2.4 The table is at its row cap — cannot add records

Cause: row count hit the per-table limit.

Fix: reconfigure the automation; pick a different table.

### 2.5 The workflow was disabled mid-run — execution terminated

Cause: the workflow author disabled the workflow during execution.

Fix: re-enable the automation as needed.

### 2.6 HTTP request timeout

Cause: HTTP requests have a 20s response cap — anything longer is dropped.

Fix: ask the upstream side to return faster — they need to respond within 20s for AI Table to receive the result.

### 2.7 HTTP response format invalid — please check it matches the request response format

Cause: the **Send HTTP request** response auto-included default Content-Type header values, which can't be parsed.

Fix: clear the default header values and retry.

### 2.8 HTTP request URL blocked — please ensure it's reachable on the public internet

Cause: HTTP requests don't support intranet URLs.

Fix: switch to a public URL.

### 2.9 This attachment field is mobile-only — please reconfigure

Cause: the attachment field is set "mobile photo capture only", which automation can't change.

Fix: reconfigure — uncheck "mobile photo capture only" on the field, or pick a different field.
