If using azure container apps, you have to setup postgrest separately as a side car container.

If you are using docker setup, try adding this env in your .env file if not present.

PGRST_DB_PRE_CONFIG=postgrest.pre_config

v3.20.45-lts

This issue is fixed in this version. So try using it or above.

If you are below this version try adding the above env that would work, If not working try upgrading to the version(or above) mentioned. If still not working put a message in the slack community.

Hope this helps.
