Troubleshooting: "Next Step" Drop-down Fields are Empty

Issue:

When using "Next Step" fields to transition samples to next workflows in a workflow chain, the "Next Step" drop-down list is empty.

Root Cause: As an ESP 3.0.2 performance improvement, all occurrences of the expression

{{ next_node_choices() }} should be replaced with {{ next_node_choices_ht() }}

There is an issue with mounted volumes and the data directory in ESP 3.0.2 that masks these newer Core queries

In ESP 3.0.2, the Docker Volume at the ~/data/ dir is a part of the deployment process

At that point, all files are 'snapshotted' there, and this has implications due to the fact that ESP updates the queries in the ~/data/queries directory across ESP releases

Therefore, the newer queries are not recognized

Solution:

In ESP 3.0.2, the next_node_choices.yaml file is required to put the newer queries in place in the deployed system

This issue should be resolved in ESP future releases - please contact customer support if running ESP 3.0.2 and experiencing this issue
