Cause for Parameter is incorrect 0x80070057 error in ssis

Possible cause for the cryptic error
The package failed to load due to error 0x80070057 "The parameter is incorrect.". This occurs when CPackage::LoadFrommXML fails. 
...when opening or executing and SSIS package



In my case i created the ssis package using biml. And accidentally created a duplicate precedence constraint to another task twice. Removing the duplicate constraint and re-generating the package solved it.
