Solution skill

dbt error: env_var is undefined in profiles.yml

Version 1

Complete solution

Fixes unresolved env_var() calls in profiles.yml for analytics engineers and repair agents. Use when dbt fails at startup saying an environment variable is undefined. Not for var() errors in models or for wrong credential values.

TL;DR

profiles.yml is parsed before anything runs, and the named environment variable is not set in your shell. Export it, or add a default like envvar('DBTPASSWORD', 'fallback') if a default is safe. Then re-run dbt debug to confirm the profile connects.

Error

dbt error: env_var is undefined in profiles.yml

Steps

  1. Read the error for the variable name, then check your shell: echo $VAR_NAME (use the exact name from the error). Expected: It prints empty, confirming the variable is not set in this shell session.

  2. Export it in your current shell: export VAR_NAME='value', then re-run the dbt command. For a permanent fix add the export to your shell profile or your orchestrator's env config. Expected: The command gets past profile parsing instead of failing immediately.

  3. If a default is acceptable (dev-only values, never prod secrets), change profiles.yml to envvar('VARNAME', 'default_value') so a missing var degrades instead of crashing. Expected: dbt parses profiles.yml even when the variable is unset.

  4. Run dbt debug to verify the full profile, connection included. Expected: dbt debug reports OK on the profile and the connection test passes.

When to use

  • dbt fails immediately with env_var is undefined naming a profiles.yml variable
  • works on a teammate's machine but not yours (their shell has the export)
  • CI fails while local runs pass (CI env config missing the variable)

When not to use

  • the error is var() undefined inside a model (different mechanism, see the var skill)
  • the variable is set but the value is wrong (that is a credentials bug, not undefined)
  • the failure is a warehouse permission error after connecting

Tool compatibility

  • dbt-core all versions; profiles.yml parsing happens before adapter code
  • dbt Cloud: set env vars in the environment settings, not in profiles.yml
  • works with direnv, dotenv, and orchestrator env injection alike

Variant phrasings

env_var undefined only in dbt Cloud jobs

dbt Cloud ignores your local exports. Add the variable under the environment's variables in the dbt Cloud UI.

Runtime Error: secret env var not set

Same root cause, different error text. dbt 1.5+ raises this when the variable is marked secret and missing.

Why it happens

profiles.yml supports env_var() so secrets never live in the file, but dbt evaluates it at parse time in whatever shell launched the run. A variable exported in one terminal tab, or set only in your IDE, is invisible to the dbt process. The error is dbt telling you the lookup returned nothing.

Edge cases

  • Never commit a real secret as the default value of env_var() in profiles.yml; defaults get committed to git. Use defaults only for non-sensitive dev values.
  • On Windows, setx or the System settings panel is needed; a cmd-session set does not persist.
