What causes "Compilation Error: {message}" in dbt-labs/dbt-core?

Fix the condition described in `{message}` in the offending template/macro

Error message

Compilation Error: {message}

What it means

Same as the node-aware compilation error, but raised when `node_metadata_from_state` returns None — the rendering context has no node id/file path. The library then emits a plain `Compilation Error: {message}` so the user message still surfaces even without node context (e.g. rendering snippets outside a node).

Solutions

Fix the condition described in `{message}` in the offending template/macro
Render within a normal node context if node-level diagnostics are needed
Replace the hard raise with `exceptions.warn` while debugging

Example fix

// before
{{ exceptions.raise_compiler_error("bad input") }}
// after
{% if bad_input %}{{ log("bad input: " ~ input, info=True) }}{% endif %}  // soften while diagnosing

Defensive patterns

Strategy: try-catch

Try / catch

// Same message shape without node info:
if let Some(msg) = err.to_string().strip_prefix("Compilation Error: ") {
    handle_compiler_error(msg);
}

Prevention

Render templates within a node context when you need node diagnostics
Prefer warn() during interactive debugging
Keep template-level validations explicit about which input failed

When it happens

Trigger: A template calls `raise_compiler_error(msg)` while being rendered without node metadata in the Jinja state (ad-hoc rendering, macro evaluation outside a model context).

Common situations: Running `dbt compile`/render of standalone macros or docs blocks where no model node is attached, yet a template-level validation failed.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
