Medusa V2 candidate-4

[jkuzmanovik]

I am trying to deploy completly new Medusajs v2 candidate 4 backend to railway. Here is the meduss-config, also i am using:
"@medusajs/cache-redis": "rc",
"@medusajs/event-bus-redis": "rc",
"@medusajs/workflow-engine-redis": "rc",

,
import { loadEnv, defineConfig } from '@medusajs/framework/utils'

loadEnv(process.env.NODE_ENV || 'development', process.cwd())

module.exports = defineConfig({
projectConfig: {
databaseUrl: process.env.DATABASE_URL,
http: {
storeCors: process.env.STORE_CORS!,
adminCors: process.env.ADMIN_CORS!,
authCors: process.env.AUTH_CORS!,
jwtSecret: process.env.JWT_SECRET || "supersecret",
cookieSecret: process.env.COOKIE_SECRET || "supersecret",
},
//Worker mode
workerMode: process.env.MEDUSA_WORKER_MODE as "shared" | "worker" | "server",
//Reddis-url
redisUrl: process.env.REDIS_URL,
},
admin: {
disable: process.env.DISABLE_MEDUSA_ADMIN === "true",
backendUrl: process.env.MEDUSA_BACKEND_URL,
},
//Modules
modules: [
{
resolve: "@medusajs/cache-redis",
options: {
redisUrl: process.env.REDIS_URL,
},
},
{
resolve: "@medusajs/event-bus-redis",
options: {
redisUrl: process.env.REDIS_URL,
},
},
{
resolve: "@medusajs/workflow-engine-redis",
options: {
redis: {
url: process.env.REDIS_URL,
},
},
},
]
})

But everytime i get this error:

Error: Module @medusajs/cache-redis doesn't have a serviceName. Please provide a 'key' for the module or check the service joiner config.

I've solved it like this:

modules: [
      {
         resolve: '@medusajs/cache-redis',
         key: ModuleRegistrationName.CACHE,
         options: {
            redisUrl: process.env.REDIS_URL,
         },
      },
      {
         resolve: '@medusajs/event-bus-redis',
         key: ModuleRegistrationName.EVENT_BUS,
         options: {
            redisUrl: process.env.REDIS_URL,
         },
      },
      {
         resolve: '@medusajs/workflow-engine-redis',
         key: ModuleRegistrationName.WORKFLOW_ENGINE,
         options: {
            redis: {
               url: process.env.REDIS_URL,
            },
         },
      },
   ],

Basically adding the key property for each module. ModuleRegistrationName is imported from @medusajs/framework/utils.

This is missing from the docs, but seems to be required.

This pr sould fix this issue, in the meantime, @renequez solution works 💪

ps: if you could format the code next time it would be nice :)

[Attachai77]

I have some question. what is difference between Modules and ModuleRegistrationName from '@medusajs/framework/utils' , Could I use either ?

[olivermrbl]

@adrien2p, can we close this issue? 🙏

[adrien2p]

Yes we can 👌
@Attachai77 the registration name will be removed if not already the case. It is a legacy constant
