Remove the cell values [undefined ] or replace with N/A

[DilipChiru]

Hi Team,

I am trying the implement for one my issues relate to git-hub logs.

I have implemented and is almost working. May I know How to remove the “[undefined]” in the code of java script while send an email to the outlook .
Below is the screenshot related to it .

I would like to remove the “[undefined]” and replace it with the 0 or “N/A”.

Below is the JS which I am using it ::::

const inputArray = $input.all();

const outputMap = new Map();

inputArray.forEach((item) => {
const key = item.json.component;
const location = item.json.Location;
const count = item.json.count_Location;

if (!outputMap.has(key)) {
    outputMap.set(key, {
        count_Location: key,
        total: 0
    });
}

const existingItem = outputMap.get(key);
existingItem[location] = (existingItem[location] || 0) + count;
existingItem.total += count;

});

// Replace undefined fields with 0
const finalArray = Array.from(outputMap.values()).map(item => {
for (const key in item) {
if (item[key] === undefined) {
item[key] = 0;
}
}
return item;
});

return finalArray;

It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

You can simply add || "n/a" after each value that may be undefined. You can do that in your code block or in an expression in a field. In the case a value is undefined or falsey, it will use the value to the right of the ||.

Example:

inputArray.forEach((item) => {
  const key = item.json.component || "n/a";
  const location = item.json.Location || "n/a";
  const count = item.json.count_Location || "n/a";
}

Then you don’t need any extra logic to change the values. You can also use || "0" if you prefer.

Hi @liam ,

Thanks for the reply. Still we see the same issue event after applying the changes ::

[liam]

Please share the input data json and I will write the code to fix

[DilipChiru]

Hi @liam ,
Basically, The input is the combination of the 2 things, One is with the raw data. as an example below ::

items[0].json.someArray = [
{
“repo_id”: 4251,
“repo_name”: “service”,
“component”: “ABC”
},
{
“repo_id”: 7845,
“repo_name”: “king”,
“component”: “RTS”
} ]
return items;

2nd is getting from the http request to get the repo_id with the username ::

{
“aggs”: {
“repository_project_id”: {
“terms”: {
“field”: “repository.project.id”,
“order”: {
“_count”: “desc”
},
“size”: 5000
},
“aggs”: {
“user_name”: {
“terms”: {
“field”: “user.name”,
“order”: {
“_count”: “desc”
},
“missing”: “-”,
“size”: 5000
}
}
}
}
},
“size”: 0,
“script_fields”: {},
“stored_fields”: [
“*”
],
“runtime_mappings”: {},
“_source”: {
“excludes”:
},
“query”: {
“bool”: {
“must”: [
{
“match_all”: {}
}
],
“filter”: [
{
“match_phrase”: {
“repository.project.id”: “{{ $json.repo_id }}”
}
},
{
“range”: {
“@timestamp”: {
“gte”: “now-1M”,
“lt”: “now”,
“format”: “strict_date_optional_time”
}
}
}
],
“should”: ,
“must_not”:
}
}
}

Based on the 2 inputs , I am trying to get the username, I am trying to get the Location from the LDAP AD Group and below is the screenshot related to workflow.

Please help me

[liam]

Please send full valid JSON

Where are the locations coming from?

What are the numbers in this table representing?

Hi @liam ,

Let me explain and provide you the input and output.

Step 1: First I am collecting the raw input and pushing it through the “code” & ItemList module . Like this I have 50 repo_id ::

items[0].json.someArray = [
{
“repo_id”: 4251,
“repo_name”: “service”,
“component”: “ABC”
},
{
“repo_id”: 7845,
“repo_name”: “king”,
“component”: “RTS”
} ]
return items;

Step 2 : I am getting the “repo_id” & “username” from the http_request using elastic search api query from the git-logs.

{
“aggs”: {
“repository_project_id”: {
“terms”: {
“field”: “repository.project.id”,
“order”: {
“_count”: “desc”
},
“size”: 5000
},
“aggs”: {
“user_name”: {
“terms”: {
“field”: “user.name”,
“order”: {
“_count”: “desc”
},
“missing”: “-”,
“size”: 5000
}
}
}
}
},
“size”: 0,
“script_fields”: {},
“stored_fields”: [
“*”
],
“runtime_mappings”: {},
“_source”: {
“excludes”:
},
“query”: {
“bool”: {
“must”: [
{
“match_all”: {}
}
],
“filter”: [
{
“match_phrase”: {
“repository.project.id”: “{{ $json.repo_id }}”
}
},
{
“range”: {
“@timestamp”: {
“gte”: “now-1M”,
“lt”: “now”,
“format”: “strict_date_optional_time”
}
}
}
],
“should”: ,
“must_not”:
}
}
}
Step 3: Once I get the list of user.name from the http_request. I am separating them using itemList & set Module to get the user.name then I am pasing into LDAP AD group to get the Location using user.name :

Step 4: Then I am using merge module for the "Step1 & Step 3 " to combine the both the data using merge by position.

Step 5 : Then I am using set module to get the list of repo_id , Component & Location .

Step 6: Later I am transposing the Component into column and Location into rows to get the count.

Once I done with these steps I am sending into an email.

Currently, I am seeing [undefined] in the code module. Please help me here to set it as “0” or N/A

Thanks

You need to send the JSON right before your “Code1” node.
I am not able to see what your workflow is doing to the data just from a screenshot.

Go to where you took this screenshot below and copy the JSON from the panel to the left.
I could guess with the code but that might waste both of our time, i need to see the actual input to the code I need to write
