dbt.exceptions.CompilationError: 'list' object has no attribute 'get'

Not specified by the original author.

[Arpit Solanki (accepted answer)] findall returns a list so you can't use get method on it. If you are sure that alarmTime exists in every node of xml then use the code below import xml.etree.ElementTree as ET tree = ET.parse('sample.xml') root = tree.getroot() for elem in root: print(elem.findall('alarmTime')[0].get('id')) Another possible solution is to use find function but it will throw error if it can't find alarmTime in element node import xml.etree.ElementTree as ET tree = ET.parse('sample.xml') root = tree.getroot() for elem in root: print(elem.find('alarmTime').get('id'))

TL;DR

A macro treated a list like a dictionary. Find the variable, check its real shape (often the result of run_query, a var, or modules output is a list of rows), and index or loop it instead of calling .get. Printing the variable with log() during compile shows the true structure fast.

dbt.exceptions.CompilationError: 'list' object has no attribute 'get'

Use this when

• dbt compile or run fails with CompilationError list object has no attribute get
• the failing code is a macro iterating config, vars, or a query result
• the error appeared after changing a var from a mapping to a list, or after a package upgrade changed a return type

Not for this skill when

• the object really should be a dict, fix the YAML var definition shape instead of the macro
• the error is dict has no attribute for a different method, inspect that call instead
• you are writing plain Python outside dbt, where this Jinja context does not apply

Steps

1. Locate the .get call: run dbt compile with --debug, find the macro and line in the traceback, and open that macro. Verify: you know the exact expression calling .get and the variable it is called on.

2. Add a temporary log call just above it, for example log(varname and varname[0] or var_name, info=true), then compile one model to see whether the value is a list and what its first element looks like. Remove the debug log afterwards. Verify: the logged output shows the real type and shape of the variable.

3. Fix the access pattern: if it is a list of dicts, loop over items and call .get on each item, or index the intended element first. If it came from run_query, use the table rows or columns API instead of dict access. Verify: the macro accesses elements with the correct type at each step.

4. Recompile the affected models and run one end to end. Verify: dbt compile and dbt run succeed with no attribute error and the rendered SQL is unchanged apart from the fix.

Variant phrasings

var defined as a list in dbt_project.yml

Vars preserve YAML types. A var written with dash lines is a list even if the macro author expected a mapping; align the macro or the var, and document the shape.

results from a hook

The results object in on-run-end is a list of result objects, not a dict keyed by model. Loop it and filter by node name.

Compatibility: dbt-core 1.x Jinja environment (Jinja2) for macros, models, and hooks; YAML vars keep their YAML types on all adapters.

Why it happens

Jinja in dbt is dynamically typed: nothing stops a macro from calling a dict method on a list until render time. Upstream data shapes (vars, query results, package return values) decide the real type, and when one of them is a list of records rather than a single record, .get fails immediately with this CompilationError.

Edge cases / pitfalls

• An empty list hides the bug until data exists; test the macro with empty and multi-row inputs.
• Chained .get calls fail on the first wrong type, so fixing one call may reveal the next; recompile after each fix.
• Do not convert with a blind dict() call; a list of pairs and a list of dicts need different handling.

TL;DR

You treated a dict like an object with a missing key. In jinja, mydict.somekey raises when the key is absent. Switch the access to mydict.get('somekey') or guard with an if key in dict check. Find every place the dict is built and confirm the key actually exists there.

Error

dbt jinja error: dict object has no attribute

Steps

1. Read the error line: it names the attribute, e.g. dict object has no attribute 'database'. Search your model and macros for that attribute access. Expected: You find the exact spot, usually something like relation.database or config.get(...) chained into dot access.

2. Trace where the dict comes from. Common sources: var() returning a dict, adapter.get_relation returning None-ish, or a hand-built dict missing a key for one code path. Expected: You know which dict is missing which key, and for which inputs.

3. Replace dot access with .get('key') plus a sensible default, or add {% if 'key' in my_dict %} around the access. Expected: dbt compile passes on the model; the missing-key path takes the default instead of raising.

4. Run dbt compile --select the model, then dbt run --select it to confirm runtime behavior too. Expected: Compile clean, run succeeds, downstream refs resolve.

When to use

• compilation fails with dict object has no attribute during dbt compile, run, or test
• you access var() or config values with dot notation
• macro code does relation.database or similar on a possibly-partial dict

When not to use

• the error is 'X' is undefined (that is a missing variable, not a dict key)
• the attribute is on a model ref that does not exist (that is a ref error)
• the failure is at warehouse runtime, not jinja render

Tool compatibility

• dbt-core all recent versions, jinja2 behavior is the trigger
• dbt Cloud shows the same compile error in the IDE
• dbt compile reproduces it without touching the warehouse

Variant phrasings

dict object has no element

Same family, but for list index access like my_list[3] on a short list. Fix with a length check or a default.

NoneType object has no attribute in jinja

The dict itself was None, not just missing a key. Guard the whole object: {% if my_dict %} before touching its keys.

Why it happens

Jinja lets you use dot notation on dicts as shorthand for key access, but unlike python attribute access it raises AttributeError instead of returning anything falsy when the key is missing. dbt surfaces that as a compile error. It usually means one code path builds the dict without the key your template assumes.

Edge cases

• var('my_var') returning different shapes per target is a classic trigger; print the var with dbt compile and a debug log line to see the real shape.
• Chained access like a.b.c fails on the first missing key; fix from the leftmost object outward.
