[CT-3236] [Bug] When adding a new version of model `foo` - partial parsing runs into a Compilation error 'model.my_dbt_project.bar' depends on 'model.my_dbt_project.foo' which is not in the graph!

[jeremyyeo]

Is this a new bug in dbt-core?

• [X] I believe this is a new bug in dbt-core
• [X] I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

Looks similar to #8859

When adding a new model version (i.e.foo_v2.sql) - partial parsing appears to not be able to find the previous version of the model even though the foo.sql file exist. Things work correctly when doing a full parse (i.e. dbt clean / delete target/ folder first).

Expected Behavior

Partial parsing should be able to detect the previous model file.

Steps To Reproduce

1. Project setup.

# dbt_project.yml
name: my_dbt_project
profile: all
config-version: 2
version: "1.0.0"

models:
  my_dbt_project:
    +materialized: table

# models/schema.yml
version: 2
models:
  - name: bar
  - name: foo

-- models/bar.sql
select * from {{ ref('foo') }}

-- models/foo.sql
select 1 as id

2. Build project to create initial target/partial_parse.msgpack file:

$ ls target

ls: target: No such file or directory

$ dbt clean && dbt build

21:27:08

21:27:08  Completed successfully
21:27:08  
21:27:08  Done. PASS=2 WARN=0 ERROR=0 SKIP=0 TOTAL=2

3. Add a new version of foo (new .sql file + changes to schema yml file):

-- models/bar.sql
select * from {{ ref('foo') }}

-- models/foo.sql
select 1 as id

-- models/foo_v2.sql
select 1 as id

# models/schema.yml
version: 2
models:
  - name: bar
  - name: foo
    latest_version: 1
    versions:
      - v: 1
      - v: 2

Thanks for reporting this @jeremyyeo! And thank you for the nice reprex above 🤩

Indeed, this does look similar to https://github.com/dbt-labs/dbt-core/issues/8859.

I'm going to leave this as a stand-alone issue since your example looks unique since it is triggered by a new model version (rather than a property change like in #8859).

We may consolidate these into the same issue in the future though.

[dbeatty10]

We should check if this is resolved by https://github.com/dbt-labs/dbt-core/pull/8865

@dbeatty10 This appears not to be resolved. I followed the repro steps above on dbt 1.7.13 and I'm still seeing the same error.

$dbt run -m foo bar
20:00:16  Running with dbt=1.7.13
20:00:17  Registered adapter: postgres=1.7.13
20:00:17  Encountered an error:
Compilation Error
  'model.my_dbt_project.bar' depends on 'model.my_dbt_project.foo' which is not in the graph!

[dbeatty10]

Thanks for checking this and sharing the result @karenderer ! 🏆

Workaround

There's a handful options for workarounds in the meantime -- all of which should only need to be done a single time.

1. Disable partial parsing for a single build

dbt build --no-partial-parse

2. Clean out the target folder with the dedicated dbt clean command

dbt clean && dbt build

3. Manually delete the entire target folder that contains the partial_parse.msgpack file

rm -rf target

4. Manually delete just the partial_parse.msgpack file within the target folder

rm target/partial_parse.msgpack

[karenderer]

Thank you! Disabling partial parsing seems to do the trick for now - appreciate the fast reply!

[pmartincalvo]

Just wanted to chime in to say that my team is currently encountering this behaviour.

The proposed workarounds do work and implementing them in our production executions has been trivial (so many thanks about that, you saved my friday afternoon), but it's been quite unpleasant having to communicate to everyone in our dbt project about them, and will continue to be.

Looking forward to a fix that will make us free from having to remind everyone that they need to clean their target everytime they run anything, just in case some other colleague has introduced a new version.
