I would like to know if ethtx tasks can be used with webhook jobs. I tried to run the job from the operator UI and it returns an internal server error, when I look up the logs it says that
Expected at least one task to be final pipeline/common.go:212 logger=1.2.1@168d34a stacktrace=github.com/smartcontractkit/chainlink/core/services/pipeline.TaskRunResults.FinalResult
/chainlink/core/services/pipeline/common.go:212
which I assume it means it cannot work unless ethtx is a final task such as jsonparse/multiply etc
Webhook jobs are limited in the task flow I believe, such that there is no support for webhook jobs and on-chain tx's related to that webhook job. In general, node operators utilize webhook jobs, to verify there job-spec code within the "observationSource" such that a bridge api endpoint is properly connected, and filtering to the correct path that the downstream user wants. Because there is no on-chain tx recorded, the testing can be done immediately after job-creation and no test smart contract to ping the oracle/node.
