Don't worry about it. I'd say a solid 5% of chip passports worldwide probably don't work. In fact within the five eyes group (Canada, US, Australia, NZ and the UK), passports can verified electronically anyway just with the machine readable zone. Passport/document scanners will automatically fall back if no chip is read.
