Kommo Modules parseCustomFields error

Hello
I’m using Kommo modules in Make.com and get this error.

Here are the details:
Module: Kommo Create Lead
Error: Function ‘formatTimestamps’ finished with error! Function
‘parseCustomFields’ finished with error! Bad escaped character in JSON
at position 19
Error screenshot:

JSON:

[
{
“name”: “Test”,
“_embedded”: {},
“contacts_id”: [
10970556
],
“pipeline_id”: 9342195,
“custom_fields_values”: [
{
“values”: [
“{"value":
"Europe\Business+Travel\W\32-55\Eng_120211406325940691"}”
],
“field_id”: 754744,
“field_code”: “UTM_CONTENT”
},
{
“values”: [
“{"value": "Facebook_Mobile_Feed"}”
],
“field_id”: 754746,
“field_code”: “UTM_MEDIUM”
},
{
“values”: [
“{"value":
"1609\Leads\Europe\Static_120211406325860691"}”
],
“field_id”: 754748,
“field_code”: “UTM_CAMPAIGN”
}
]
}
]

I think that bad escaped characters are:

{
“values”: [
“{"value":
"Europe\Business+Travel\W\32-55\Eng_120211406325940691"}”
],
“field_id”: 754744,
“field_code”: “UTM_CONTENT”
}

{
“values”: [
“{"value":
"1609\Leads\Europe\Static_120211406325860691"}”
],
“field_id”: 754748,
“field_code”: “UTM_CAMPAIGN”
}

Kommo module adds additional symbol \ to escape \ in the initial strings:

incoming string
Europe\Business+Travel\W\32-55\Eng_120211406325940691

final string
Europe\Business+Travel\W\32-55\Eng_120211406325940691

I don’t apply any escape functions, it’s applied by the Kommo module itself.

Without these fields, I save the leads w/o any errors.

how to avoid it? only by replacing \ with empty space?
