How to delete certain collection from array

[Kamil]

I am having trouble deleting a collection from array on the basis of “number” value.
Anyone could give me a hint?

Hello Kamil,

Could you add the JSON file corresponding to your example?
It will be useful for experimentation.

so there is no universal rule to archieve it?

this is an array:
“blf array”: [
{
“number”: “45104010002”,
“title”: “Sławomir - ŁH”
},
{
“number”: “45104010027”,
“title”: “Sławomir - ŁM”
}
]

And I want to delete one of the entries, I have a “number” value of the collection I want to remove

You can use an Iterator and Array Aggregator, with a filter in-between.
