I am trying to parse an array of json, But I am getting the following error

TypeError: string indices must be integers

Json:

{

    'locationId': 'location1',

    'name': 'Name',

    'type': 'Ward',

    'patientId': None,

    'children': [{

        'locationId': 'location2',

        'name': 'Name',

        'type': 'Bed',

        'patientId': None,

        'children': [{

            'locationId': 'location3',

            'name': 'Name',

            'type': 'HospitalGroup',

            'patientId': None,

            'children': None

        }]

    }, {

        'locationId': 'location4',

        'name': 'Name',

        'type': 'Hospital',

        'patientId': None,

        'children': None

    }, {

        'locationId': 'location5',

        'name': 'Name',

        'type': 'Bed',

        'patientId': None,

        'children': None

    }, {

        'locationId': 'location6',

        'name': 'Name',

        'type': 'Bed',

        'patientId': None,

        'children': None

    }, {

        'locationId': 'location27',

        'name': 'Name',

        'type': 'Bed',

        'patientId': None,

        'children': None

    }]

}

I am trying to the get all the locationId values and store the values one by one inside a list.

Here is what I am doing

    @{locationIds}=  create list

    :FOR  ${item}  IN   @{Location_Json}

      ${locationId}=  set variable  ${item['locationId']}

      log  ${locationId}

      append to list  ${locationIds}  '${locationId}'

I have also tried this

    @{locationIds}=  create list

    :FOR  ${item}  IN   @{Location_Json}

      ${locationId}=  set variable  ${item['children'][0]['locationId']}

      log  ${locationId}

      append to list  ${locationIds}  '${locationId}'

But I am getting the same error.

The test is failing on this line ${locationId}= set variable ${item['locationId']}

Any help would be apprectiated.

If the content of the var ${Location_Json} is indeed the json sample you've put above, that would explain the exception "string indices must be integers".

The json you are working with is a dictionary (not a list); thus, in this loop:

:FOR  ${item}  IN   @{Location_Json}

, the value of ${item} is going to be the keys in the in the dictionary - e.g. locationId, name, etc of the top-level dictionary.

If you are interested in the "locationId" of the "children" subdict, that will do it - iteration over the "children" items:

:FOR ${item} IN @{Location_Json['children']}

On each iteration the ${item} is going to be one of the sub-dicts in "children", and you can get its "locationId"

    ${locationId}=  set variable  ${item['locationId']}

Not related to your issue, put please do not do that:

append to list  ${locationIds}  '${locationId}'

Do not put the value of ${locationId} inside the single quotes - what will happen is those quotes will now be a part of the list member.

Say, the value of ${locationId} is

location5

with those quotes surrounding it, it will end up as

'location5'

I don't think that's your goal; with these extra quotes, this will fail:

Should Be Equal As Strings    location5      ${locationIds[3]}   # because locationIds[3] will have the extra quotes
