Mule flat file mapping: “com.mulesoft.flatfile.lexical.WriteException – effective length * is greater than * for component…” – alternative solution

This falls under the category “strange error messages” in Mule. Normaly you would think that the data you send is bigger than the longest allowed value, but in my case it was because I was trying to map a value from an array without setting a index

Tested in Anypoint Studio 7.11.1 and Mule 4.3
