Prisma Pool Timeout in prisma v7

[HamamPriyatmoko]

Question

I have a problem with my Prisma v7, initially I was told to add an adapter, then I added the MariaDB adapter and after adding it I got a pooltimeout error. Why is that? Can anyone explain?

The error: "{
message: 'pool timeout: failed to retrieve a connection from pool after 10013ms\n' +
' (pool connections: active=0 idle=0 limit=5)',
target: 'members.findUnique',
timestamp: 2025-12-26T09:54:42.336Z
}"

file schema:
" generator client {
provider = "prisma-client-js"
engineType = "client"
binaryTarget = ["native"]
}

datasource db {
provider = "mysql"
} "

Hey @HamamPriyatmoko!

Can you provide a minimal reproduction?

Based on the snippets you have shared, in the schema.prisma file for Prisma 7 you don't need these configurations:

engineType = "client"
binaryTarget = ["native"]

and you can replace provider = "prisma-client-js" with provider = "prisma-client".

[HamamPriyatmoko]

Oh, thanks! It works. I replaced prisma-client-js with prisma-client. I originally thought that if we use vanilla JavaScript, we had to use prisma-client-js. Also, just to clarify: is it actually possible to import a .ts file into a .js file?

[nurul3101]

I am glad to hear that it works. You would need to transpile the TypeScript file in order to use it from a .js file

changing to provider="prism client" will cause an error in the console. May I ask why this is happening?

I will execute prisma generate again

P1013: The provided database string is invalid. invalid port number in database URL. Please refer to the documentation in https://pris.ly/d/config-url for constructing a correct connection string. In some cases, certain characters must be escaped. Please check the string for any illegal characters.

[HamamPriyatmoko]

First, you typed it incorrectly. It should be provider="prisma-client".
You can check it here.

Second, based on the error message, your database connection URL is wrong.
You can find the correct format here
