org.jpos.iso.IFB_LLLHNUM: Problem unpacking field 44 (org.jpos.iso.ISOException: Field length 3634 too long. Max: 25) unpacking field=44, consumed=87

Question

I have been trying send a flag in ISO 8583 spec - in field 40 which will yield 44 field in response.

Seeing the below error...

all other field gets unpacked just fine expect this filed 44.

ISOPACKAGER:

/*Field 44 */  new IFB_LLLHNUM(25, "EOV Date", true),  //has to be Ascii

I tried truncating the field 44 to size 25.

Saw this on logs: seems like it's returning some ASCII special characters while receiving the msg we are seeing this error, whereas the request is reaching them just fine.
