Exception reported: Property "m_iItemDefinitionIndex" not found (entity 327/weaponworldmodel)

public Action OnWeaponCanUse(client, weapon)
{
	decl String:sweapon[64];
	GetEdictClassname(weapon, sweapon, sizeof(sweapon));
	new weaponindex = GetEntProp(weapon, Prop_Send, "m_iItemDefinitionIndex");

this error happens very rarely and crash server
after this code (EquipPlayerWeapon):

zweapon[client_index] = GetEntPropEnt(client_index, Prop_Data, "m_hActiveWeapon");
if (IsValidEntity(zweapon[client_index]))
{
	RemovePlayerItem(client_index, zweapon[client_index]);
}	
else zweapon[client_index] = -1;

then:

if(zweapon[client_index] != -1 && IsValidEntity(zweapon[client_index])) EquipPlayerWeapon(client_index, zweapon[client_index]);

what it is - weaponworldmodel?
how should i fix this?

zweapon[client_index] = GetEntPropEnt(client_index, Prop_Data, "m_hActiveWeapon");
char sweapon[64];
GetEdictClassname(zweapon[client_index], sweapon, sizeof(sweapon));
if (IsValidEntity(zweapon[client_index]) && StrContains(sweapon, "weapon_") != -1)
{
	RemovePlayerItem(client_index, zweapon[client_index]);
}
else zweapon[client_index] = -1;

will fix crash?

You can fix it by storing the Entity Reference into zweapon[client_index] instead of the entity index.
EntIndexToEntRef(weapon);
EntRefToEntIndex(weapon);
Don't forget to check if the active weapon is valid before converting it to a reference and validating it after you convert it back to an index.
