LUA error: attempt to call field 'GetQuestWatchType' (a nil value)

[schroeg]

I often get this lua error. Open guide: The Barrens (12-15)

If you have all other addons disabled do you still get this error?

[schroeg]

Leveling without any addons is not feasible for me since this error does not always occur.

But I did disable all addons and did a print of the function:

/script print(C_QuestLog.GetQuestWatchType, GetQuestWatchType)
Result both are nil, see image 1a and 1b

1b-WoWScrnShot_081321_125651.jpg
/script print(C_QuestLog.RemoveQuestWatch, RemoveQuestWatch)
Result first is nil second is a function pointer. see image 2a and 2b.

Of course you will get a nil when you use those scripts. You never supplied the required quest ID in the script. You would also need the quest in question to still be active in your logs and being watched but it looks like you only have 1 quest in the watch list which is not the one that was referenced in the LUA error.

[schroeg]

Yes I know I did print the function on purpose without parameters. In this case it should print a function pointer if the function exists in the table.

The outcome of /dump C_QuestLog
[15:40:02] Dump: C_QuestLog
[15:40:02] C_QuestLog={
[15:40:02] GetQuestObjectives=<function>,
[15:40:02] GetMaxNumQuestsCanAccept=<function>,
[15:40:02] GetQuestInfo=<function>,
[15:40:02] GetMaxNumQuests=<function>,
[15:40:02] ShouldShowQuestRewards=<function>,
[15:40:02] IsOnQuest=<function>,
[15:40:02] IsQuestFlaggedCompleted=<function [PlayerCompletedQuest]>
[15:40:02] }

Here you can see that the function GetQuestWatchType is not present in this table.

Doing the same on the retail client then the function does exists.
