Re-index search data migration fails

[euanmillar]

In Somalia, the re-index search data migration failed in the search microservice because for some reason there is a null value in the Task extensions array.

The Task extensions array looks like this:

"extension": [
{
"url": "http://opencrvs.org/specs/extension/informants-signature",
"valueString": "/ocrvs/b7bd427e-ae9a-4c7c-a5b0-691e66b26d08.png"
},
{
"url": "http://opencrvs.org/specs/extension/contact-person-phone-number",
"valueString": "******"
},
null,
{
"url": "http://opencrvs.org/specs/extension/regLastUser",
"valueReference": {
"reference": "Practitioner/03044936-738e-4f45-a145-d2af4b82bba1"
}
},
{
"url": "http://opencrvs.org/specs/extension/regLastLocation",
"valueReference": {
"reference": "Location/a7ea1e4e-ea52-45e4-8ef4-bd5ce2434f7f"
}
},
{
"url": "http://opencrvs.org/specs/extension/regLastOffice",
"valueString": "Beledweyn CR Office (BW)",
"valueReference": {
"reference": "Location/6c8adfc2-783e-4afc-9225-337581c42d28"
}
}
]

While we are unsure how a null value could have entered the extensions array, a solution could just be to handle null values appropriately.

Occurs in 1.6.*
