+If you are working on a Mac with an Apple Silicon chip, you may need to specify the platform for your Hasura image in your docker-compose.override.yml file as well.  If so, your file would look like this:
+
+```
+services:
+  odinson-rest-api:
+    volumes: 
+      - [yourfilepath]/data/odinson:/data/odinson
+  hasura:
+    platform: linux/amd64
