I'm dynamically setting the value on a PictureBox to a api controller that resizes the image from storage and returns the bytes.

ex: https://localhost:44300/company-logos/4?width=96

 

Getting this error:

An error has occurred while processing PictureBox 'Logo':
Invalid image data.
------------- InnerException -------------
Too many automatic redirections were attempted.

 

This was working fine up until a couple weeks ago. Not sure what changed to be honest.

 

If I access the route directly, the controller works as expected (returns the resized image). When setting it in the report, the controller never gets called.

 

If I set the value to an external source, it's working. Of course the image isn't resized though.

ex: https://somedomain.blob.core.windows.net/logos/00000004/635939217942995665_FullSizeRender.jpeg

Hi Gordon,

The issue is new for us and we need further details. Can you attach a Trace Listener to the project hosting the Reporting engine and send us the generated log when the issue occurs? I hope our code will log the exact Stack Trace of the error.

Which Reporting version do you use?

How do you render the report? In an Html5 Viewer, in a Report designer, in a desktop viewer?

What changed in the environment just before the problem started?

Hi Todor - Thank you for replying.

 

Can't attach txt file, so there's a screen cap. Not sure what's causing the redirects (xhr/cookies?).

 

Ver. 2018.2.516 HTML5 viewer.

 

We recently updated to ASP.NET 4.8

Hi Gordon,

The log tells me that the URL https://localhost:44300/company-logos/4?width=96 returns HTTP status 302 Found. But it does this multiple times and I am not sure what is the reason for that. URL redirects are usually configured in the application's configuration file. Please check the application to see if such rules have been defined.
