Hello Stardew Valley Modding Community, Love this game and all the wonderful mods the community has to offer. I have been playing for about 20 hours now in a multiplayer game (I am the 2nd player) with my wife and cannot load into the game this morning. I get an error in the game upon trying to load my multiplayer character as follows in SMAPI 3.0.0. Code: [11:12:19 ERROR game] An error occured in the base update loop: System.InvalidOperationException: There was an error generating the XML document. ---> System.NullReferenceException: Object reference not set to an instance of an object. at JsonAssets.Overrides.ObjectDisplayNameHook.Prefix(Object __instance, String& __result) in G:\StardewValley\Mods_1.4\JsonAssets\Overrides\Object.cs:line 80 at loadDisplayName_Patch1(Object ) at StardewValley.Object.get_DisplayName() in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Objects\Object.cs:line 266 at Write42_Object_Patch2(Object n, String ns, String o, Object isNullable, Boolean needType, Boolean ) at Write43_Item_Patch2(Object n, String ns, String o, Item isNullable, Boolean needType, Boolean ) at Write74_Farmer_Patch2(Object n, String ns, String o, Farmer isNullable, Boolean needType, Boolean ) at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriterFarmer.Write75_Farmer(Object o) --- End of inner exception stack trace --- at System.Xml.Serialization.XmlSerializer.Serialize(XmlWriter xmlWriter, Object o, XmlSerializerNamespaces namespaces, String encodingStyle, String id) at System.Xml.Serialization.XmlSerializer.Serialize(Stream stream, Object o, XmlSerializerNamespaces namespaces) at Netcode.NetRefBase`2.serialize(BinaryWriter writer, XmlSerializer serializer) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Netcode\NetRef.cs:line 93 at Netcode.NetRefBase`2.WriteFull(BinaryWriter writer) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Netcode\NetRef.cs:line 234 at Netcode.NetRoot`1.CreateConnectionPacket(BinaryWriter writer, Nullable`1 connection) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Netcode\NetRoot.cs:line 113 at StardewValley.Multiplayer.writeObjectFullBytes[T](NetRoot`1 root, Nullable`1 peer) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Network\Multiplayer.cs:line 627 at StardewValley.Network.Client.sendPlayerIntroduction() in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Network\Client.cs:line 178 at StardewValley.Menus.FarmhandMenu.FarmhandSlot.Activate() in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Menus\FarmhandMenu.cs:line 33 at StardewValley.Menus.LoadGameMenu.update(GameTime time) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Menus\LoadGameMenu.cs:line 1141 at StardewValley.Menus.FarmhandMenu.update(GameTime time) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Menus\FarmhandMenu.cs:line 190 at StardewValley.Menus.TitleMenu.update(GameTime time) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Menus\TitleMenu.cs:line 1242 at StardewValley.Game1.updateActiveMenu(GameTime gameTime) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Game1.cs:line 4069 at StardewValley.Game1._update(GameTime gameTime) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Game1.cs:line 3599 at StardewValley.Game1.Update(GameTime gameTime) in C:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Game1.cs:line 2875 at Update_Patch1(Object gameTime, GameTime ) If anyone on the forums can help me out that would be great. Full log is available here. https://pastebin.com/YvZHQyzB (log.smapi.io keeps timing out and is unable to create a parse of my logs).
@Dauf Smapi.io is being updated to handle the higher load it's been getting and will be back soon. The pastebin isn't easy to read, but from looking at what you posted above, I would say start by updating Json Assets. Also, make sure that you and your wife have exactly the same mods when playing multi.
@Moragaine Thanks for the help with this issue. JsonAssets has been updated to the latest version 1.5.1 on both computers. Additionally, my wife and I are running the exact same mods on both computers, but only I am getting this error. Not sure what happened. I'll try to post the parsed log using the log.smapi.io log parser once the site has been updated. Thanks again.
Log parse for analysis. https://smapi.io/log/0ryzmGCs Looks like there is a game error. Not sure what I am do to about this.
Same error occurred ~17 hours into my second character on the same multiplayer file. All mods are the same on both machines. Log parse for analysis. https://smapi.io/log/G5kTcZ6u Looks like there is the same game error that occurred with the last character.
@Dauf This seems to be a bug in JsonAssets (or at least related to it). The error happens in JsonAsset code. You should ask on the mod page for help or report this as a bug. I think your problem has to do with an item on your character that is missing information. (This might have something to do with a change in stardew 1.4 that added the "DisplayName" field for objects.)
@jahangmar Thank you for the response and suggestion on what to do. I've reported the issue to the mod page on nexus mods. Thanks again!
