When i use a Crypter Object i have a error with Power builder 2017 , because it close . 

The error happen when i change the key and no use the key in the example :

Blob lblb_data
Blob lblb_key
Blob lblb_iv
Blob lblb_encrypt
Blob lblb_decrypt

lblb_data = Blob("Test AES", EncodingANSI!)
lblb_key = Blob("Test Key12345678", EncodingANSI!)
lblb_iv = Blob("Test IV 12345678", EncodingANSI!)

CrypterObject lnv_CrypterObject
lnv_CrypterObject = Create CrypterObject

// Encrypt data using AES
lblb_encrypt = lnv_CrypterObject.SymmetricEncrypt(AES!, lblb_data, lblb_key, &
	OperationModeCBC!, lblb_iv, PKCSPadding!)

// Decrypt data using AES
lblb_decrypt = lnv_CrypterObject.SymmetricDecrypt(AES!, lblb_encrypt, lblb_key, &
	OperationModeCBC!, lblb_iv, PKCSPadding!)

messagebox("SymmetricDecrypt", string(lblb_decrypt, EncodingANSI!))

I change key  "Test Key12345678" for "QuIpUx+D3/hJ*?--*/@3" and the program close , What can i do ? Please help me
