Remove tags with Automation

This code seems to be working for me to remove a specific tag:

{
"tags":[{% assign oldTagList = ticket.tags | split: ", " %}{% for thisTag in oldTagList %}{% unless thisTag == "TAG_TO_REMOVE" %}"{{thisTag}}"{% if forloop.last == false %},{% endif %}{% endunless %}{% endfor %}]
}

I faced two problems with this code:

1. If i have more than one TAG and the TAG I’m looking for is the last one, it doesnt work
2. I receive following email again and again:

   

BTW What a cool idea and solution (y). hope you can help me to solve my problems :)

All I can think would be to check for extraneous whitespace.

Can you post your code?

https://webhook.site/ is helpful for troubleshooting to see exactly what is being sent to the webhook. 

it’s your code from July 20th:

{
"tags":[{% assign oldTagList = ticket.tags | split: ", " %}{% for thisTag in oldTagList %}{% unless thisTag == "Waiting" %}"{{thisTag}}"{% if forloop.last == false %},{% endif %}{% endunless %}{% endfor %}]
}

i only adapted the “TAG_TO_REMOVE”

{
"tags":[{% assign oldTagList = ticket.tags | split: ", " %}
    {% for thisTag in oldTagList %}
        {% if forloop.last == false and forloop.first == false %},
        {% endif %}
        {% unless thisTag == "Waiting" %}"{{thisTag}}"
        {% endunless %}
    {% endfor %}]
}

i moved the forloop last to the top and included the forloop.first. due this webhook only runs if the tag is there this works for me :)

This is exactly what I’m looking for as well, but unfortunately I keep getting the failure emails showing ‘Request body has invalid json format’. Any ideas? I’ve tried both options in this thread (full text below).

{
"tags":[{% assign oldTagList = ticket.tags | split: ", " %}
    {% for thisTag in oldTagList %}
        {% if forloop.last == false and forloop.first == false %},
        {% endif %}
        {% unless thisTag == "action" %}"{{thisTag}}"
        {% endunless %}
    {% endfor %}]
}

I’ve also tried this and get the same error

{
"tags":[{% assign oldTagList = ticket.tags | split: ", " %}{% for thisTag in oldTagList %}{% unless thisTag == "action" %}"{{thisTag}}"{% if forloop.last == false %},{% endif %}{% endunless %}{% endfor %}]
}

there was still a bug in my code so this is the final version which works doesnt matter on which position the tag in the list is:

{
"tags":[
    {% assign TagToDelete = "TAG_TO_REMOVE" %}
    {% assign oldTagList = ticket.tags | split: ", " %}
    {% assign TagCounter = 1 %}
    {% for thisTag in oldTagList %}
        {% unless thisTag == TagToDelete %}
            "{{thisTag}}"
        {% endunless %}
        {% assign TagCounter = TagCounter | plus: 1 %}
        {% if forloop.last == false and thisTag != TagToDelete %}
            {% unless forloop.length == TagCounter and oldTagList.last == TagToDelete %}
                ,
            {% endunless %}
        {% endif %}
    {% endfor %}]
}

last and only problem is that i receive those emails:
