@Marvin why did my

DbtCloudJob

fail even when I check my DBT cloud it says it succeeded? I got the error:

Finished in state Failed('Flow run encountered an exception. JSONDecodeError: Expecting value: line 1 column 1 (char 0)')

The error you're seeing can be due to issues in how the response from the DBT Cloud API is being parsed in your Prefect flow. It's possible that Prefect is attempting to parse a response that is either empty or not valid JSON, resulting in a

JSONDecodeError

. Here are a few steps to troubleshoot and resolve this issue: 1. Enable Detailed Logging: Enable DEBUG logging for more detailed logs which can help diagnose the issue.

python
   import os
   
   os.environ["PREFECT_LOGGING_LEVEL"] = "DEBUG"

2. Validate DBT Cloud Credentials: Ensure that your DBT Cloud credentials and job configuration are correct. Example for Prefect 2.x:

python
   from prefect_dbt.cloud import DbtCloudJob
   from prefect import flow

   @flow
   def run_dbt_cloud_job():
       dbt_cloud_job = DbtCloudJob.load("YOUR_JOB_BLOCK_NAME")
       result = dbt_cloud_job.run()
       return result

   run_dbt_cloud_job()

Example for Prefect 3.x:

python
   from prefect_dbt.cloud import DbtCloudCredentials, DbtCloudJob
   
   dbt_cloud_credentials = DbtCloudCredentials.load("YOUR_CREDENTIALS_BLOCK")
   dbt_cloud_job = DbtCloudJob(
       dbt_cloud_credentials=dbt_cloud_credentials,
       job_id="YOUR_JOB_ID"
   ).save("YOUR_JOB_BLOCK_NAME")
   
   @flow
   def run_dbt_cloud_job():
       job = DbtCloudJob.load("YOUR_JOB_BLOCK_NAME")
       job.run()
   
   run_dbt_cloud_job()

3. Checking DBT Cloud Response: Inspect the response from DBT Cloud within the code to ensure it is valid and contains the expected data.

python
   result = dbt_cloud_job.run()
   print(result)  # Inspect the result to check for issues

4. Update Prefect and DBT Integration: Ensure you are using the latest versions of Prefect and the

prefect-dbt

integration. For more information, refer to: - Prefect 2.x DBT Cloud Jobs: https://docs-2.prefect.io/latest/integrations/prefect-dbt/cloud/jobs/ - Prefect 3.x DBT Cloud Jobs: https://docs-3.prefect.io/integrations/prefect-dbt/index If the above steps do not resolve the issue, please provide more details about your configuration and any additional logs, and I'll be happy to assist further!

attempting to parse a response that is either empty or not valid JSON

yep, if you have more of the trace, it would be helpful to see where it came from

interesting, looks like the util in

prefect-dbt

should handle this case can you share the output of

prefect version

?

Here is the full output:

Version:             2.13.0
API version:         0.8.4
Python version:      3.11.9
Git commit:          66577cc6
Built:               Thu, Sep 7, 2023 3:52 PM
OS/Arch:             darwin/arm64
Profile:             default
Server type:         cloud

aha, sorry one more if you could. older versions of prefect dont show the integration versions in this command

pip list | grep prefect-dbt

Here it is:

*prefect-dbt*        0.3.1

thank you! i will look into this

Thanks Nate!
