I am facing same error for MaxLength . I have changed it to - DataSourceInfo([@Table1],MaxLength,"Id") , still I can see same error. Is there any other way to fix it?
Solved! Go to Solution.
The 3rd param is the column name
DataSourceInfo function intellicense will let you pick specific column names
Not all column types work

Hi @AzureLearner ,
The right syntax of DataSourceInfo function is :
DataSourceInfo( DataSource, Information, ColumnName )
The information shoule be the format like this:
DataSourceInfo.DisplayName
DataSourceInfo.MaxLength
DataSourceInfo.MaxValue
So, try this formula:
DataSourceInfo([@Table1],DataSourceInfo.MaxLength,"Id")
Here's a doc about this function for your reference:

Workaround hack for the DataSourceInfo-always-true bug.
1. Create a new Sharepoint list with 1 row
2. Grant read permission only to the group you want to test
3. Add a hidden Gallery control to your PowerApp that refers to your new list
4. The Gallery will only load rows if the user has that permission, so use CountRows to test this.

Hi, I assume MaxLength doesn't work well with CDS data source?
