Error applying a ConfigMap which contains a string with numbers and multiple commas

[davidcaste]

Bug report

I have a minimal ConfigMap with the following contents:

apiVersion: v1
data:
  SPECIAL_PHONE_NUMBERS: 799999990,799999991,799999992,799999993,799999994,799999995,799999996,799999997,799999998
kind: ConfigMap
metadata:
  name: foo-bkk2tbth72

krane is not able to deploy it and throws the following error:

It seems like it got confused with the first comma, and it tried to parse the value as a Number instead of just a String.

Expected behavior: Apply the manifest without complains.

Actual behavior: It fails with the error above.
