'MemorySize' value failed to satisfy constraint: Member must have value less than or equal to 3008

Whenever i try to increase the memory above 3008 MB of my lambda function, i get the error: 'MemorySize' value failed to satisfy constraint: Member must have value less than or equal to 3008. Although it says i can Set the memory between 128 MB and 10240 MB, and i am in a supported region for setting the memory above 3008MB (us-east-1 - AWS Lambda now supports up to 10 GB of memory and 6 vCPU cores for Lambda Functions), its still giving me the error, i'm honestly stuck because i keep getting the error: Error: Runtime exited with error: signal: killed which requires more memory, but i cant set it higher than 3008 MB.
