IndexOptimize Script Failed

I have a scheduled maintenance job that IndexOptimize provided by one of the sql server expert (Ola Hallengren).

The job is scheduled and it succeeded in my other SQL Server Instances except for one of the Instance that return error when the job was run.

Here is the job step.

Schedule Job Step:

EXECUTE dbo.IndexOptimize @Databases = 'USER_DATABASES',
@FragmentationLow = NULL,
@FragmentationMedium = 'INDEX_REORGANIZE,INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
@FragmentationHigh = 'INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
@FragmentationLevel1 = 5,
@FragmentationLevel2 = 30,
@UpdateStatistics = 'ALL',
@OnlyModifiedStatistics = 'Y',
