Hi there everyone,
I am after some help please with the following...
I have upgraded from Akka 2.4.17 to 2.5.0
I have copy / pasted the reference configuration from the 2.5.0
documentation - completely replacing all 2.4.17 configuration.
And I have also read the 2.4 to 2.5 migration guide - but my issue doesn't
seem to be covered in there.
Also - it seems to be a Play issue... but as I have only updated Akka not
Play, here seemed appropriate - so I hope that's OK?
I am using;
* Scala 2.11.8
* Akka 2.5.0
* Akka HTTP 10.0.5
The only change I have made is to upgrade Akka and replace the Akka
configuration files.
As a result of the upgrade my app throws a 500 error when attempting to
load any fixed / public asset.
An example of what is causing the error is below;
<script src = "@routes.Assets.at("javascripts/jquery/jquery-3.1.1.min.js")"
></script>
which causes the following stack trace;
19:59:20.319 [application-akka.actor.default-dispatcher-5] - [error] -
application -
! @73lillnl9 - Internal server error, for (GET) [/assets/javascripts/jquery/
jquery-3.1.1.min.js] ->
