Failed to repair report: ReportProcessingException while extending render

I can generate the report in SSRS 2008, but when I try to generate it again, it works with below error. However, it will work again after restarting SSRS. What configuration option can affect this? (I've added all the required extensions.)

SSRS seems to be trying to load an assembly that contains some report rendering functionality (maybe some charts you added)?



If so, this article explains how to register a DLL using SSRS.

It turned out that the problem is that SQL Web Edition doesn't support html extensions. You need a minimum of Standard. Why it worked remains a question.

In our case, the problem is that through the API we requested a report and tried to convert the report from HTML to another extension. And unfortunately, the specific configuration file of the Reporting Services instances was not configured \ extended to support the requested render format.

In MS SQL Server 2008-R2 the configuration file is located in a directory structure that looks like this:

 E:
   \Program Files
      \Microsoft SQL Server
         \MSRS10_50.MSSQLSERVER_RS
            \Reporting Services
               \ReportServer

And, the actual filename is rsreportserver.config

Find the "Render" section in the config file:

<Configuration>

<Extensions>

<Render>

In the Render section, find the corresponding Extension entry. If the extension is not found, add it:

0
