n8n-expression-syntax

Fix n8n expression syntax errors by wrapping variables in double curly braces, quoting node names with spaces, and maintaining exact case sensitivity for node references. This validation prevents common workflow failures.

n8n webhook expressions fail when the data path is incorrect. Access webhook payloads by targeting the .body property within your expression to properly retrieve incoming JSON data from the trigger node.

Use $json and $node variables in n8n expressions by enclosing them in {{ }} syntax. Ensure node names with spaces are quoted and match exact casing to avoid reference errors during workflow execution.

Correct n8n expression syntax avoids nested braces entirely. Wrap the entire expression in a single set of {{ }} and use standard JavaScript syntax inside to access data without causing parsing errors.

Yes, you can use $now and $env variables in n8n workflow expressions. Wrap them in {{ }} syntax to correctly evaluate current timestamps and environment variables within your automated workflows.

n8n expressions break when referencing other nodes if the node name contains spaces but is not wrapped in quotes, or if the node name casing does not match exactly. Validate references to prevent workflow errors.
