When trying to create views in Looker from a table (located in BigQuery), i sometimes get this error and the lookML of the view is not correctly generated.

#X# Conversion failed: failed to parse YAML.  Check for pipes on newlines

Anybody has had similar problems?


A workaround for me is now manually writing the LookML for the view, but that’s a time consuming task for code that could be auto-generated

I’m having the same issue. I think for me at least it has to do with column description in BigQuery for structs.

When I try generating the view from the table after removing the column descriptions it’s not an issue. I think  the new feature for generating field descriptions from the BigQuery descriptions (added in release 21.4) could have something to do with it.

Hi @mathias.luyten and @Avi, Thanks for the post! I see a similar report internally. @Avi is spot on in regard to the description being the cause.


Would you be able to tell me which version/patch on 21.4 you are using please? It appears this should be resolved in the latest build. 


Please let me know if you have any questions.

Hi Eric, thanks for replying. Currently using Looker 21.4.17

Should we manually update to a newer version?
