EACCEPT returns SGX_PAGE_ATTRIBUTES_MISMATCH

If enclave_alloc succeeds with a virtual address in-enclave, what reasons would running EACCEPT on the address fail afterwards? I get an error message when I run eaccept on a virtual address which has been previously alloced via enclave_alloc.

The return code I get matches: SGX_PAGE_ATTRIBUTES_MISMATCH, how do i fix this?

I see that someone has the psuedo code for it here: https://github.com/Mic92/x86_64-linux-cheatsheats/blob/master/pages/ENCLU%5BEACCEPT%5D

How do I know what the correct EPCM page attributes are?
