BUG: KeyNotFoundException (and fix) fsRecoveryProcessor

[drumstig]

hi,

when i tried building some assetbundles containing flowcanvas, the following error occured

“KeyNotFoundException: The given key was not present in the dictionary.”

after some digging i found that the problem was inside “fsRecoveryProcessor.cs”

..

13.        private const string FIELD_NAME_TYPE = “_missingType”;

14.        private const string FIELD_NAME_STATE = “_recoveryState”;

..

however, inside the OnBeforeDeserialize(Type storageType, ref fsData data) function
the data.AsDictionary  keys for missingType and recoveryState do not contain an underscore.

for now i simply removed the underscore inside the fsRecoveryProcesser.cs file, and that seems to fix it.

*note: i noticed that the other keys inside data.asDictionary contained an underscore, so this might not be a permanent solution,but it does the trick for now.

Hello,

 

Hmm. Did you maybe recently upgraded FlowCanvas, but between the upgrade you already had some missing nodes in some of your graphs by any chance?

The serialized fields definetely do contain the underscore (you can confirm this by opening up the MissingNode.cs file for example), but this has recently changed. Thus, the only way I can see this happening is if you upgraded with some Missing Nodes already existing in some of your graphs like stated above.

I would not really recomend making the change you mentioned because it would break the funcionality of finding missing node types and recovering them.

 

Please let me know.

Thank you.

hi,

yes i did an update to flowcanvas and it probably contained some missing nodes.
im in the process of taking over a project, still searching for the flow script with the missing nodes

for now i added an extra check on both with and withouth underscores

OnBeforeDeserialize(
…

var json = data.AsDictionary;
FIELD_NAME_TYPE  = (json.ContainsKey(“_missingType”)) ? “_missingType” : “missingType”;
FIELD_NAME_STATE = (json.ContainsKey(“_recoveryState”)) ? “_recoveryState” : “recoveryState”;
…

Hey,

Thanks for the follow up. Yep, I think this should work until all “missing nodes” are resolved (either removing them or creating/importing the missing type.

Thanks!
