Cannot match integer value using regex - error (at <stdin>:6): number not a string or array

I have multiple JSON files with a person's age and I want to match specific ages using regex, however, I cannot be able to match even a single integer in a file.

I can select age using following jq,

jq -r .details.Age

I can match Name using following jq,

jq -r 'select(.details.Name | match("r.*"))'

But when I try to use test or match with Age I get following error,

jq -r 'select(.details.Age | match(32))'
jq: error (at <stdin>:6): number not a string or array

Here is code,

{
  "details": {
    "Age": 32,
    "Name": "reverent"
  }
}

I want to be able to match Age using jq something like this,

jq -r 'select(.details.Age | match(\d))'

Your .Age value is a number, but regexes work on strings, so if you really want to use regexes, you would have to transform the number to a string. This can be done using tostring, but please remember that the tostring representation of a JSON number might not always be what you think it will be.

p.s. That should be match("\\d")
