PlayFramework 2.4.6 error 413 Request Entity Too Large

For those who are facing issue with Play Framework 2.6.x see documentation at https://www.playframework.com/documentation/2.6.x/ScalaBodyParsers

Max content length Text based body parsers (such as text, json, xml or formUrlEncoded) use a max content length because they have to load all the content into memory. By default, the maximum content length that they will parse is 100KB. It can be overridden by specifying the play.http.parser.maxMemoryBuffer property in application.conf:

add following in application.conf:

play.http.parser.maxMemoryBuffer = 5MB

Solved the problem with this:

play.http.parser.maxDiskBuffer = 100MB

parsers.anyContent.maxLength = 100MB

I was having the same problem sending a large form and play.http.parser.maxMemoryBuffer=4MB solved it.

See this documentation about the memory and disk buffers Play uses: https://www.playframework.com/documentation/2.4.x/ScalaBodyParsers#Max-content-length

Text based body parsers (such as text, json, xml or formUrlEncoded) use a max content length because they have to load all the content into memory. By default, the maximum content length that they will parse is 100KB. It can be overridden by specifying the play.http.parser.maxMemoryBuffer property in application.conf:

play.http.parser.maxMemoryBuffer=128K

For parsers that buffer content on disk, such as the raw parser or multipart/form-data, the maximum content length is specified using the play.http.parser.maxDiskBuffer property, it defaults to 10MB. The multipart/form-data parser also enforces the text max length property for the aggregate of the data fields.

So, since you're trying to uploading a multipart file, you'll need to increase the play.http.parser.maxDiskBuffer to something >18MB.

So, adding this to your application.conf should fix it:

play.http.parser.maxDiskBuffer=100MB
