TypeError: string indices must be integers

[elrezad]

Hi! Since last Friday I'm having an error when running records=app.get('object_8')

throwing this: `File "/usr/local/lib/python3.7/dist-packages/knackpy/formatters.py", line 118, in identifiers = [conn["identifier"] for conn in value] TypeError: string indices must be integers'

I'm able to get other objects (much smallers, the one that is giving problem has 8.5k records x 25 columns), so the problem should be on that db. Any suggestions of where or what should I look for?

Thanks

@elrezad sorry to hear of your error. I believe you've encountered a bug. Would you be able to provide your app ID, or at least copy/paste the object_8 field list from the knack explorer output?

Hey @johnclary, this isn't my issue but I believe I've been able to repro this for one of our apps.

For us, it had to do with aa random string of characters in one of our _raw fields (I have raised this issue internally with Knack as well, but just wanted to let you know).

The specifics are as follows:

• a fetch from Knack's native API for object_1 for a specific record responds with the following (obfuscated just cause we don't know what it is and don't want to publish it lol)

  "field_457": "",
  "field_457_raw": [
      "A",
      "B",
      "C",
      "D",
      " ",
      "E",
      "F",
      "G",
      "H",
      "I"
  ],

• this record is in object_1
• field_457 is a Connection to object_39

When knackpy pulls this record down and begins looping through each fields' formatters,

• the line of code here
• with value equal to ['A', 'B', 'C', 'D', ' ', 'E', 'F', 'G', 'H', 'I'] (field_457_raw)
• tries to build a list comprehension on field_457_raw that fails because the letter "A" doesn't have a field "identifier". And so on for letters B-I

I will let you know what I hear back from Knack about this, as it's really upstream of knackpy. If you'd like me to raise a PR anyways for

-         identifiers = [conn["identifier"] for conn in value]
+         identifiers = [conn["identifier"] for conn in value if "identifier" in conn]

let me know.

App-specific output for that app:

Connections

Retailer | object_39 | field_457 | outbound | one | many

Fields

Retailer | field_457 | connection
