Hi everyone! 🌈 I am trying to use the "import via manifest.json" to import the assets from a dbt project. I used the same code written in the docs, but I receive this error: AttributeError: 'str' object has no attribute 'read'. I checked with an online tool and mi JSON is perfectly valid. What could be the problem here? 🤨

Based on the error message I’d think you need to pass a file object instead of a stringified JSON. maybe something like:

with open('manifest.json') as f:
  load_assets_from_dbt_manifest(f)

why not load with

load_assets_from_dbt_project

though?

I am trying to use this method to check if it allows to run one singular model at a time after importing all of them at once. Right now I am importing one model at a time, like this:

dbt_assets_1 = load_assets_from_dbt_project(project_dir=DBT_PROJECT_DIR, select="first_dbt")

dbt_assets_2 = load_assets_from_dbt_project(project_dir=DBT_PROJECT_DIR, select="second_dbt")

dbt_assets_3 = load_assets_from_dbt_project(project_dir=DBT_PROJECT_DIR, select="third_dbt")

dbt_assets_4 = load_assets_from_dbt_project(project_dir=DBT_PROJECT_DIR, select="fourth_dbt")

In this way I can select only one model in the dag and run it singularly, but the downside is that I need to define each asset.

If you’re selecting the assets it should only run one, if you’re running it from a job, you can always do something like

[define_asset_job(asset) for asset in loaded_assets]

(obviously untested, probably need a few more parameters)

hmm,

load_assets_from_dbt_manifest

shouldn't expect a file object. mind sharing the full stack trace?
