request body is empty. line 30 of xforms-server.xpl, but why and and how to fix it?

[saadatimoghadam]

Hello everyone
I am using personal services and I encountered this error and I don't know where to check to understand the problem.

This is cause, meaning the request body is empty.
line 30 of xforms-server.xpl

<p:processor name="oxf:url-generator">
<p:input name="config"
href="aggregate('config', aggregate('url', #request-body#xpointer(string(/request/body))))"/>
<p:output name="data" id="xforms-request"/>
</p:processor>

Hi Mohammad,

What is "personal services"?

This error is often caused by a request incorrectly having an empty body. To debug this, I recommend implementing the HttpLoggingFilter. You can find more information about it in the section linked below. Please let us know what you discover.

Hi dear Alex
I was using a different context path and prologue-servlet.xpl was directing all paths to the page-flow.xml even js and css files

Hi Mohammad,

Great, I'm glad you solved the problem, and thank you for the update.
