I'm getting an error when I try to create a DLT Pipeline from a bunch of third-party app-usage data we have. Here's the error message:

Found invalid character(s) among ' ,;{}()\n\t=' in the column names of your schema.

Please upgrade your Delta table to reader version 2 and writer version 5

and change the column mapping mode to 'name' mapping. You can use the following command:

ALTER TABLE <table_name> SET TBLPROPERTIES (

'delta.columnMapping.mode' = 'name',

'delta.minReaderVersion' = '2',

'delta.minWriterVersion' = '5')

So, I added the properties to my table definition, and I'm still getting the error. What am I doing wrong? Here's the table definition:

CREATE STREAMING LIVE TABLE clevertap_analytics_bronze 

 COMMENT "App usage data from CleverTap" 

 TBLPROPERTIES ("myCustomPipeline.quality" = "bronze",

  "delta.columnMapping.mode" = "name",

  "delta.minReaderVersion" = "2",

  "delta.minWriterVersion" = "5"

)
