Debugs and fixes dbt errors systematically. Use when working with dbt errors for: (1) Task mentions "fix", "error", "broken", "failing", "debug", "wrong", or "not working" (2) Compilation Error, Database Error, or test failures occur (3) Model produces incorrect output or unexpected results (4) Need to troubleshoot why a dbt command failed Reads full error, checks upstream first, runs dbt build (not just compile) to verify fix.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# dbt Troubleshooting

**Read the full error. Check upstream first. ALWAYS run `dbt build` after fixing.**

## Critical Rules

1. **ALWAYS run `dbt build` after fixing** - compile is NOT enough to verify the fix
2. **If fix fails 3+ times**, stop and reassess your entire approach
3. **Verify data after build** - build passing doesn't mean output is correct

## Workflow

### 1. Get the Full Error

```bash
dbt compile --select <model_name>
# or
dbt build --select <model_name>
```

Read the COMPLETE error message. Note the file, line number, and specific error.

### 2. Inspect Actual Data (For Data Issues)

**Before fixing "wrong output" or "incorrect results", query the actual data:**

```bash
# Preview current output
dbt show --select <model_name> --limit 20

# Check specific values with inline query
dbt show --inline "select * from {{ ref('model_name') }} where <condition>" --limit 10

# Compare with expected - look for patterns
dbt show --inline "select column, count(*) from {{ ref('model_name') }} group by 1 order by 2 desc" --limit 10
```

**Understand what's wrong before attempting to fix it.**

### 3. Read Compiled SQL

```bash
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add altimateai/data-engineering-skills/debugging-dbt-errors@sha256:3a32473f71da8784

The line at the top of this page pins the label git:20260121.476f750, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
