Get mismatch info?

[pablote]

I'm currently struggling to determine why two objects that look the same to me are being compared as being different.

Is there anyway for me to get information as to why the lib is returning false? either as part of the response or just logging would help.

thanks

I had "faulty positive" situation too.

JSON.stringify() values were indentical:

{"tag":"CAT","ind1":" ","ind2":" ","subfields":[{"code":"b"}{"code":"h","value":"1035"}]}
{"tag":"CAT","ind1":" ","ind2":" ","subfields":[{"code":"b"}{"code":"h","value":"1035"}]}

After a while i started to console log whole objects and found out that JSON.stringify() drops undefined values:

{
  tag: 'CAT',
  ind1: ' ',
  ind2: ' ',
  subfields: [
    { code: 'b' },
    { code: 'h', value: '1035' }
  ]
}
{
  tag: 'CAT',
  ind1: ' ',
  ind2: ' ',
  subfields: [
    { code: 'b', value: undefined },
    { code: 'h', value: '1035' }
  ]
}```
