error not found while installing

[koendegroote]

hi, magento 2 dutch informal language pack is giving an error: not found. I have tried both methods of installing pack from composer as well as from command line, both methods giving errors.

thanks, Koen

The XML in file "/srv/magento/vendor/mageplaza/magento-2-dutch-informal-language-pack/language.xml" is invalid: Element 'code': [facet 'pattern'] The value 'nl_di' is not accepted by the pattern '[a-z]{2}([a-zA-Z]{4})?[A-Z]{2}'. Line: 3 Element 'code': 'nl_di' is not a valid value of the atomic type 'codeType'. Line: 3 Verify the XML and try again.
