KeyNotFoundException in TokenParser.GetListTitleForMainLanguage

Hello,

when using ClientContext.Web.ApplyProvisioningTemplate we sometimes get this exception:

System.Collections.Generic.KeyNotFoundException: The given key 'NameOfTheList' was not present in the dictionary. at System.Collections.Generic.Dictionary2.get_Item(TKey key) at PnP.Framework.Provisioning.ObjectHandlers.TokenParser.GetListTitleForMainLanguage(Web web, String name) at PnP.Framework.Provisioning.ObjectHandlers.TokenParser.RebuildListTokens(Web web) at PnP.Framework.Provisioning.ObjectHandlers.ObjectListInstance.ProvisionObjects(Web web, ProvisioningTemplate template, TokenParser parser, ProvisioningTemplateApplyingInformation applyingInformation) at PnP.Framework.Provisioning.ObjectHandlers.SiteToTemplateConversion.ApplyRemoteTemplate(Web web, ProvisioningTemplate template, ProvisioningTemplateApplyingInformation provisioningInfo, Boolean calledFromHierarchy, TokenParser tokenParser) at Microsoft.SharePoint.Client.WebExtensions.ApplyProvisioningTemplate(Web web, ProvisioningTemplate template, ProvisioningTemplateApplyingInformation applyingInformation)

We are at this moment using PnP.Framework 1.7.0, but we noticed the same problem already in version 1.6.0. Before we were working the the "old" PnP-Sites-Core library and we were able to provision without any problems.

Please advice.

Kind regards,

Domen

Start at TokenParser.GetListTitleForMainLanguage and trace its callers through RebuildListTokens and ObjectListInstance.ProvisionObjects when Web.ApplyProvisioningTemplate runs. Reproduce the intermittent KeyNotFoundException with the reported list name and determine why that name is absent from the dictionary; done means provisioning completes without the exception.
