Copy Dataverse data from ADLS Gen2 to Azure SQL DB leveraging Azure Synapse Link

shireenbahadur  I try to use this template, but hare stucked with error like this:

{ "errorCode": "2200", "message": "ErrorCode=AdlsGen2OperationFailed,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=ADLS Gen2 operation failed for: 'filesystem' does not match expected pattern '^[$a-z0-9](?!.*--)[-a-z0-9]{1,61}[a-z0-9]$'.. Account: 'rndatalake'. FileSystem: '@split(triggerBody().folderPath,''. Path: '')[0]/@split(triggerBody().folderPath,'/')[1]/OptionsetMetadata/GlobalOptionsetMetadata.csv'..,Source=Microsoft.DataTransfer.ClientLibrary,''Type=Microsoft.Rest.ValidationException,Message='filesystem' does not match expected pattern '^[$a-z0-9](?!.*--)[-a-z0-9]{1,61}[a-z0-9]$'.,Source=Microsoft.DataTransfer.ClientLibrary,'", "failureType": "UserError", "target": "Copy GlobalOptionsetMetadata", "details": [] }

When I google it, I found several people having the same problem, but no solution. Any suggestion?
