Do we still need this line? It seems the function parameter error_handling is still there.

[derrickaw]

I was getting this failure when running with it:
FAILED apache_beam/yaml/integration_tests.py::ExplodeTest::test_Explode_ExternalJavaProvider_WriteToJson_ExternalJavaProvider_3 - ValueError: Error applying transform at line 101: Transform 'beam:schematransform:org.apache.beam:yaml:explode:v1' was configured with unknown fields: {'error_handling'}. Valid fields: {'fields', 'cross_product'}

[derrickaw]

I reverted the error_handling doc string deletion and made another TODO to investigate further in conjunction with the other todo. Thanks!

[shunping]

I left a minor comment, but mostly LGTM. Thanks!

I think the two failing checks are not related to this PR.

What is the plan to continuously test these yaml examples?

[tvalentyn]

nvm, these are test pipelines.
