Maximum size limit for Object Size on AWS Signer for platform AmazonFreeRTOS

Question

I was trying to create an OTA update job on AWS IoT Core. I ran into an error when trying to specify AWS to sign a file for me. When I attempted to create the file, there is an error on Object size exceeds the maximum size for platform AmazonFreeRTOS-Default (Service: AWSsigner; Status Code: 400; Error Code: ValidationException; Request ID: xxxxxxxxxx; Proxy: null) where the file I attempt to sign is 196 KB. I searched around but I didn't see any resources on the max object size limit on this and fix. So I decided to post it here for help.

Is there a max object limit that AWS Signer can sign for platform AmazonFreeRTOS? Is there a way to configure the size to be lift up the limit? If not, does that mean I have to use custom file sign?

Thank you in advance

Accepted Answer

Is there a figure for "maxSizeInMB" in the response? That should be set to

> The maximum size (in MB) of the payload that can be signed by the target platform.
