Hello, when I want to open page, this error occured: 

 

This error happens when the server cannot serialize the data to be sent to the client.
A common cause is that one attribute's length exceeds the defined maxlength in the projection.
To find more info, open Log Window or Debug Console, refresh and then check Network Tab in DevTools. In the response there can be more detailed information about the exception.
Error details: N/A

 

I open DevTools → Network and in this operation was status code 200, I dont know what should I do

Hi ​@Ed22,

You can track this by looking at the network tab in the dev tools. There should be a clue there.

    Hi ​@Ed22,

    The reason for this error is that the maximum length of an attribute in your page has been exceeded.

    From database, check which one is causing this.

    How do I find out which column it is?

    Could you look at the view definition in the database and then compare the data lengths to the corresponding field in Page Designer?  I had received a similar error, and it happened when a field on page designer had a max length of 1000, but the field in the view was defined as VARCHAR2(200).

      In network → response I see only this: “"<ERROR>{"error":{"code":"ODP_SERIALIZATION_ERROR","message":"Error while serializing content."}}</ERROR>”

      Hi Ed,
      I have a script to analyze ORACLE “objects”. Means tables and views.
      I use mainly a MS SQL version because all my stuff is located on a MS SQL based BI-Server.
      But the core parts of these scripts you can use with PL SQL or Toad or even within IFS query.

      So what view do you use?

      Please be aware: most of the API fields result in varchar(4000) fields.
