esgmigrate and esgpublish disagree on field name (project_cfg vs user_project_config)

[pchengi]

Version of esgpublish: v5.2.4

When esgmigrate is used to convert a project's ini file, it generates a yaml file with a field project_cfg. When this file is then parsed by esgpublish, it prints a warning same project config could not be parsed.
When the field is renamed to user_project_config, the warning disappears.
