Hello,

I am implementing RSA encryption of JSON data in D365FO using a public key extracted from a .pem file.

The solution works correctly in UAT and Performance, but fails in Production with the following error during batch execution:

Unable to find manual secret value
The given key was not present in the dictionary
Batch task failed: KeyNotFoundException

Initially, the public key was read from Azure Key Vault. To rule this out, I moved the key to a table memo field, but the same error occurs in Production only.

Since the code and configuration are identical across environments, I suspect a production-specific issue related to encryption handling, batch execution context or security (not aware if their is )

Any guidance on resolving this would be appreciated.

Regards,
Ayushaman
