Pharacloud Seaside Rest exception when opening the application

Hello everyone,

I have a fully working Seaside MDL application in locale.

But when I load the image (pharo 6) to ephemeric cloud and try to open the application, I get:

WAArgumentNotFoundError: argument "aPhonenumberString" was not found in #(#arg1 #arg2)

Debug Full Stack

thisContext

WAFullPlaceholderPathMatch class(WAMatch class)>>argument:notFoundInd:

self

WAFullPlaceholderPathMatch

thisContext

[ :arg3 | | tmp1 | arg3 isDigit ifFalse: [ tmp1 := arg2 indexOf: arg1. tmp1 isZero ifTrue: [ ...etc...

self

WAFullPlaceholderPathMatch

thisContext

ByteString(SequenceableCollection)>>do:

self

'aPhonenumberString'

When I use an Pharo 5 image, the Seaside welcome page doesn't show up. And I get a '500 internal server error'.

Could you help fixing this?

thanks,

Lionel
