Scala code run from Intellij Worksheet doesn't seem to be able to find the akka actor resources.
The error is:
com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'akka'
There is an opened ticket on Intellij bugtracker https://youtrack.jetbrains.com/issue/SCL-9229 with a work arround

| The default utf8 character set doesn't support emoji characters, you'll see `[SQLException: Incorrect string value: '\xF0\x9F\x98\x8A P...' for ` exception when trying to insert data. | |
| You'll need utf8mb4 character set to be able to sotre emoji characters. | |
| 1. You'll need to create all the tables with CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci option | |
| 2. After initializing the conneciton, you will need to send SET NAMES utf8mb4, | |
| you can do that with the hikari connectionInitSql option, a SQL statement that will be executed after the connetion was initialized. | |
| slick.dbs.default.db.connectionInitSql="set names utf8mb4" |

If you were playing with reactive-stream, and you got this error
scala> val sum = source.runWith(sink)
<console>:14: error: could not find implicit value for parameter materializer: akka.stream.FlowMaterializer
You need an implicit FlowMaterializer
