Finatra downloads HTML file instead of displaying it

Question

I am using Finatra 2.1.6 with this code:

get("/:*") { request: Request =>
response.ok.fileOrIndex(
  request.params("*"),
  "index.html")
}

If I run this from e.g. IntelliJ, it works perfectly fine and displays the html file. However, if I start the server from an assembled jar (using sbt assembly), it does not: Whenever I try to access index.html, which I put in src/resources/index.html, it tries to download the file since the contentType is set to application/octet-stream instead of e.g., text/html.

How can I change the behaviour so it renders the html file (or css, js,...) rather than downloading it?

Finally could solve the problem. My merge strategy for sbt assembly would be something like

val meta = """META.INF(.)*""".r
assemblyMergeStrategy in assembly := {
  ...
  case meta(_) => MergeStrategy.discard
  ...
}

which would discard the file mime.types which denotes what MIME type to use for a given file extension. I changed this to

val metaMime = """META.INF(.)mime.types""".r
val meta = """META.INF(.)*""".r
assemblyMergeStrategy in assembly := {
  ...
  case metaMime(_) => MergeStrategy.deduplicate
  case meta(_) => MergeStrategy.discard
  ...
}

and now it works perfectly fine.
