uper_encode() failed to encode ASN1 Message

[akmalns]

I tried to encode the following NZP_CSI_RS_Resource type :

/* NZP-CSI-RS-Resource */
 typedef struct NZP_CSI_RS_Resource {
	NZP_CSI_RS_ResourceId_t	 nzp_CSI_RS_ResourceId;
	CSI_RS_ResourceMapping_t	 resourceMapping;
	long	 powerControlOffset;
	long	*powerControlOffsetSS;	/* OPTIONAL */
	ScramblingId_t	 scramblingID;
	struct CSI_ResourcePeriodicityAndOffset	*periodicityAndOffset;	/* OPTIONAL */
	TCI_StateId_t	*qcl_InfoPeriodicCSI_RS;	/* OPTIONAL */
	/*
	 * This type is extensible,
	 * possible extensions are below.
	 */
	
	/* Context for parsing across buffer boundaries */
	asn_struct_ctx_t _asn_ctx;
} NZP_CSI_RS_Resource_t;

This is the code I used to encode the data structure:

      xer_fprint(stdout, &asn_DEF_NZP_CSI_RS_Resource, item);
      memset(encBuf, 0, ENC_BUF_MAX_LEN);
      encBufSize = 0;
      encRetVal = uper_encode(&asn_DEF_NZP_CSI_RS_Resource, 0, item, PrepFinalEncBuf, encBuf);
      /* Encode results */
      if(encRetVal.encoded == ENCODE_FAIL)
      {
         DU_LOG( "\nERROR  --> ENCODE UNIT TEST : Could not encode NZP CSI RESOURCE (at %s)\n",\
               encRetVal.failed_type ? encRetVal.failed_type->name : "unknown");
         DU_LOG( "\nERROR  --> ENCODE UNIT TEST : Could not encode NZP CSI RESOURCE (at %s)\n",\
               encRetVal.failed_type ? encRetVal.failed_type->xml_tag : "unknown");
         DU_LOG( "\nERROR  --> ENCODE UNIT TEST : Could not encode NZP CSI RESOURCE (at %d)\n",\
               encRetVal.failed_type ? encRetVal.failed_type->tags_count : "unknown");
         DU_LOG( "\nERROR  --> ENCODE UNIT TEST : Could not encode NZP CSI RESOURCE (at %d)\n",\
               encRetVal.failed_type ? encRetVal.failed_type->elements_count : "unknown");
      }
      else
      {
         DU_LOG("\nDEBUG   -->  ENCODE UNIT TEST : Created APER encoded buffer for NZP CSI RESOURCE\n");
      }

Assume all of the data type needed for encoding already declared (encRetVal, encBufSize, encBuf, etc).
When I run this code, I got the following message on the terminal :

ERROR  --> ENCODE UNIT TEST : Could not encode NZP CSI RESOURCE (at INTEGER)

ERROR  --> ENCODE UNIT TEST : Could not encode NZP CSI RESOURCE (at INTEGER)

ERROR  --> ENCODE UNIT TEST : Could not encode NZP CSI RESOURCE (at 1)

ERROR  --> ENCODE UNIT TEST : Could not encode NZP CSI RESOURCE (at 0)

It is very strange that the error name is INTEGER while in the data structure, there is no variable/structure related with INTEGER. Most of the data use long data type

Can you see what might be the problem here @velichkov @vlm ?
