Hello team,
I've been facing a problem for several weeks now that I can't seem to solve.
I am using npm 6.14.8, nodeJS 12.19.0 and Node Red v1.2.2.
I am not an expert on Node Red and I am trying to run a simple scenario. Send an http request via NTLM\*(node-red-contrib-http-ntlm-req)\* authentication protocol and display the response. The problem is that I get an error in the debug window ("ReferenceError: err is not defined") and no response from the request (qualified on Postman).
The complete error message :
Can you help me to understand the origin of this problem?
Thank you in advance.
Lionel

Looks like a bug in the node (using `err.message`)...

You should raise an issue on that repository.

However, looking further up that code, you will see it expects `method` to contain `'0'` or `'1'`
Looking a little further up, it shows...
```auto
switch (msg.method) {
case 'GET':
method = '0';
break;
case 'POST':
method = '1';
break;
}
```
In other words - did you set `msg.method` to "GET" or "POST" or something else?

Thank you for your reply @Steve-Mcl which helped me a lot.
I did forgot to set `msg.method` and that solved the issue.
I have a second question, maybe you can help me. Do you know how to import/upload a CA Certificate ? It would help me to specify it before the node "http-ntlm-req" and hopefully remove the "unable to get local issuer certificate" error .
Thanks again.

No, sorry, I have never used that node.
Either start a new thread (with appropriate title to attract the correct members) OR raise an issue on the repository for the author to instruct you.
e.g. `Can’t solve “ReferenceError: err is not defined”` is not a good title. I had no idea of the subject.
A title like **"unable to get local issuer certificate: `node-red-contrib-http-ntlm-req`"** tells passers by that you have an error, that it is related to certificates & the name of node you are using.

Fine, thanks again for your help.
Have a good day.
