I am receiving the following error message and is failing my form.  Note that the character count in this field is only 66.   How do I fix so that I have unlimited character count.   
 
OpenApiOperationParameterValidationFailed. The 'inputs.parameters' of workflow operation 'Create_item' of type 'OpenApiConnection' is not valid. Error details: The API operation 'PostItem' requires the property 'item/TheAsk' to be a string of maximum length '255' but is of length '395'.

    You didn't mention the destination data source, but it seems to be SharePoint.
     
    You can change the column type from "single line of text" to "Multiple lines of text" without losing any data stored in the column already.
     
    The limit for "Multiple lines of text" column is up to 63,999 characters.
    The limit for "Single line of text" column is up to 255 characters.
     
     
    I don't know of any column type that offers an "unlimited character count". In fact, Microsoft Forms has an imposed character limit!
     
    How many characters are allowed per question? Up to 4,000
     
    Hope this helps.

    Add a compose to look at the value you are adding to TheAsk property to verify that it doesn't contain leading or trailing spaces or something like that.  Then use Trim to get rid of the excess spaces.
