OK, looks like there are 2 changes to be made:
in the WildAidDemo directory:
rename stitch.json to config.json
In the config.json, set the config_version to 20200603, so the line looks like this:
"config_version": 20200603,
Alternatively, git pull the main branch for o-fish-realm. You will want to check that your local settings for your cluster name and app name haven't been overwritten, e.g. start from step 3 on https://wildaid.github.io/build/2020/06/09/Import-Realm-Code.html
