CAPI tag throws error if conversionValue is undefined #14
Description
Hi @SurendraJambe / @SurendraJambeLI / @desaip / @wyattr,
There is an error in the tag template. If you're not supplying the tag with a conversion value, the tag will throw an error because it's trying to parse data.conversionValue which is undefined. The JSON.parse(data.conversionValue) will then throw an error saying: "undefined" is not valid JSON.
Even though the line of code uses an or statement, it still throws an error as the JSON.parse can't parse the undefined value and then throws an error.
The relevant line: https://github.com/linkedin-developers/linkedin-capi-tag-template/blob/main/template.tpl#L264
This could be solved by adding a try catch. Please let me know if you'd like me to make a PR.
