TypeError: Cannot read properties of undefined (reading 'match') about iso_8583

[zemuldo]

You are initializing with integer values. Iso data should be in strings. For example "3": 501000, should be "3": "501000",

There is some bug with the library with formats checker but it's not related to your issue. For you, you just need to convert your integer data types to strings and should work.

Some of your fields also have non-standard formats for example field 7 should be 10 numbers while yours is 9. For these you will need to define custom formats too

For more details refer to https://en.wikipedia.org/wiki/ISO_8583 or the guide to the ISO interface you are forwarding the message.

Ok great I was able to figure this out using the wiki link you shared. However, The processor I am connected to wants field 127 like below

I tried specifying a custom format like below but to no avail

'127': {
        ContentType: 'ans',
        Label: 'Postilion Private Field',
        LenType: 'llllllvar',
        MaxLen: 800000000,
        MinLen: 10
    },

[zemuldo]

This seems this is not standard implementation because the encoding does not include the bitmap for 127 thus this library will throw an error. We can allow provision to have a custom implementation of 127 that lets you pass and encoding and decoding function that matches your implementation. Would this help?

Or bake this in and let you specify how the library should treat the field.

    },

Does this still require the message to contain a bitmap for field 127?

[riliwanrabo]

Yes

[zemuldo]

So for example in your message, we shall have
bitmap + fields 0-127 + field 127.1-63 Bitmap + field 127 as key=value; is this correct?

Best case is you provide an example of the json and the expected output that we can refer to
