psa_generate_key failed! (Error: -134)

Question

I am using NCS 3.0.0 and I want to generate keys ... But the method I am using to generate keys is giving me this error Here is the code where it is returning error: 
 
 psa_set_key_usage_flags ( & key_attributes , PSA_KEY_USAGE_SIGN_HASH | PSA_KEY_USAGE_DECRYPT | PSA_KEY_USAGE_EXPORT ); 
 psa_set_key_lifetime ( & key_attributes , PSA_KEY_PERSISTENCE_VOLATILE ); 
 psa_set_key_algorithm ( & key_attributes , PSA_ALG_RSA_PKCS1V15_SIGN ( PSA_ALG_SHA_256 )); 
 psa_set_key_type ( & key_attributes , PSA_KEY_TYPE_RSA_KEY_PAIR ); 
 psa_set_key_bits ( & key_attributes , ( use_rsa_2048 ) ? KEY_SIZE : KEY_SIZE_1024 ); 
 
 status = psa_generate_key ( & key_attributes , & m_initial_keypair_handle ); 
 
 if ( status != PSA_SUCCESS ) 
 { 
 LOG_INF ( "psa_generate_key failed! (Error: %d )" , status ); 
 return APP_ERROR ; 
 } I need to Know How can I generate keys in NCS 3.0.0? Is there any example code for it?

The issue has been resolved. It was due to the heap size. By the this was the configuration I was using : 
 # Enable nordic security backend and PSA APIs CONFIG_MBEDTLS_LIBRARY_NRF_SECURITY=y CONFIG_MBEDTLS_PSA_CRYPTO_C=y CONFIG_MBEDTLS_USE_PSA_CRYPTO=y # Mbedtls configuration CONFIG_MBEDTLS_RSA_C=y CONFIG_MBEDTLS_PK_C=y CONFIG_MBEDTLS_PK_PARSE_C=y CONFIG_MBEDTLS_PK_WRITE_C=y 
 
 CONFIG_MBEDTLS_PK_WRITE_C=y CONFIG_MBEDTLS_PKCS1_V15=y CONFIG_CRYPTO=y CONFIG_MBEDTLS=y
