Notarization not working with ZXP installer on Catalina Mac OS

[yogitam26024844]

Hi,

I'm facing issue while creating the ZXP installer using the Notarized plugins.

We are developing a hybrid installer for InDesign (CEP extension and C++ plugins). We are creating the ZXP installer from the MXI file using the Eclipse (Adobe Extension Builder 3). The ZXP works as expected if we are using the non-notarized plugins but for Catalina OS, the plugins needs to be notarized.

We are doing following, to create the ZXP installer –

1. Build and sign the C++ plugin with Developer ID Application Certificate.
2. Created ZIP of the Plugin and then use the notarization command.
3. After the notarization done successfully. If we copy the notarized plugins to the InDesign then it works as expected on catalina OS.
4. We create the ZXP using the notarized plugins
5. After installing the ZXP, we are getting error message as "InDesign does not recognize BasicDialog.InDesignPlugin as valid plug-in".

Can anyone please assist us how we can create the ZXP to distribute the hybrid plugins?
