install.prisma_database_url

Prisma: DATABASE_URL is not set or has the wrong format

A mevcore app hosting error at the “install and build” stage.

What it means

Prisma reads the address of the database from DATABASE_URL (or DIRECT_URL), and it is empty or does not start with the protocol of the provider from schema.prisma (postgresql://, mysql://).

The error happened while installing dependencies or building the project. The new version was not started, the current one keeps running.

Typical causes

The install or build command exited with an error
Out of memory or disk space
The language or package manager version is not the one the project expects

How to fix it on mevcore

Check the variable on the «Environment» tab and the provider in schema.prisma; the panel sets DATABASE_URL when a database is connected on the «Services» tab.
