DBT: Encountered an error while generating catalog: 'dtype'

I am using dbt version 0.19.1.

I have a pipeline that automatically runs dbt docs generate whenever i push some changes to my git repository. From a certain point in time, pipelines started to fail with these error message:

Running with dbt=0.19.1
Found 776 models, 0 tests, 0 snapshots, 0 analyses, 359 macros, 0 operations, 0 seed files, 145 sources, 0 exposures

14:44:45 | Concurrency: 8 threads (target='default')
14:44:45 | 
14:45:07 | Done.
14:45:07 | Building catalog
Encountered an error while generating catalog: 'dtype'
dbt encountered 1 failure while writing the catalog

The problem is that I have many models and changes happening in the source code and it is not easy to understand from this message where the error is coming from. If I check the logs files in the logs folder they are very messy, containing debug information from all the threads, i cannot find the source of the issue.

Is there a way to understand where this issue is coming from? Is it possible to better debug dbt docs generate command?

Thank you all for your replies in advance!

Thank you Josh, adding another point to look for the error.

I suggest who have the same issues and has thousands of rows of logs like me to look for the string "Error while running" in the debug logs to find the place where the exception should have raised.

Hopes this could help someone else.

To better debug the issue you can use

dbt --debug docs generate

That will contain the debug information from all the threads, but it should also include a stack trace from where the error was raised.
