Error when trying to open .saz file

[Stéphane]

HI All,

I get the following error when trying to open .saz files.  Do you know what is happening and if I get other .saz files recorded, is there a particular setting I should look for?

Hello Stéphane,

 

It seems you are encountering a recently reported bug where SAZ archives created in Fiddler Everywhere are incompatible with Fiddler Classic, leading to the observed error in the Fiddler Classic application. The team is aware of the issue and will work on fixing the generation of SAZ files to ensure compatibility with all Fiddler products. You can track the problem from the following public GitHub thread:

 

https://github.com/telerik/fiddler-everywhere/issues/73 

 

Meanwhile, as a temporary solution, you could try opening the specific SAZ in Fiddler Everywhere (there is a free trial version you can start by downloading the app from here).

Hello everyone,

 

As an update related to the observed issue, I wanted to share that the Fiddler team has decided to keep the existing structure of the SAZ files generated from Fiddler Everywhere and Fiddler Everywhere Reporter. This will allow the new SAZ archives to support the enhanced features in our new Fiddler products and will also enable us to provide additional features and functionalities in the future. As a side effect, this also means that SAZ archives created with Fiddler Everywhere and Fiddler Everywhere Reporter won't be compatible with the old Fiddler Classic application, and the only option to work with them would be to open them in the latest versions of the said Fiddler products.
