Saiku through proxy (nginx)

[Kouki]

Hi. I'm having problems with working Saiku through proxy (nginx). Dimension filtering does not work (picture 1). By clicking on the dimensions given as follows:

If you work with Saiku no through proxy, the dimensions filtering works correctly (picture 2). And browser given as follows:

Somebody uses Saiku through nginx?

I got the same error, ¿someone knows how to fix it?

I had a similar problem with other proxy server and the solution went rewrite the schema replacing all attributes name that contained white spaces for "_" or eliminate the white spaces. For example:

old schema version <Dimension type="StandardDimension" visible="true" foreignKey="sk_natureza_ocupacao" highCardinality="false" name="Natureza Da Ocupacao" ...
after correction <Dimension type="StandardDimension" visible="true" foreignKey="sk_natureza_ocupacao" highCardinality="false" name="Natureza_Da_Ocupacao" ...

I don't know if your issue is the same but I believe that you should try this solucion
