Hello, I’m trying to use acs for one not popular vendor.  
It sends next parameters:

```

but ACS says  
2019-10-16T07:30:26.551Z [ERROR] {HiddenIP}: XML parse error; parseError=“Cannot read property ‘value’ of undefined”

could you please help me to define on which value error appears?

I use version 1.2.0-beta.0+20190731093016

The element is missing a ‘type’ attribute.

Hi,

I have the same error here. Unfortunately, I can not change the XML that is sent by the device.  
I used to use this patch:

> <https://github.com/Gudulin-Alexey/genieacs/commit/33a34d8d2834a02278fcd663d410f5a1cf5cc58f>

but it does not work anymore with the beta version.

Any change someone has an equivalent for the beta version ?

Thanks,

Hi,

Try this patch on lib/soap.ts :

```auto
133c133
< .value.trim()
---
> //.value.trim()
154c154,161
< const valueType = getValueType(valueElement.attrs);
---
> let valueType = getValueType(valueElement.attrs);
>
> if(valueType) {
> valueType = valueType.value.trim();
> } else {
> valueType = 'xsd:string';
> }
>

```

Hi,

Thanks, it better: I can now see the parameters, but most of them are blank.  
Is there a way to see what is sent by the device ? (I can not use tcpdump, as it’s over https)

Set the config `cwmp.debug` (from admin → config) to `true`. And make sure to `genieacs-cwmp` is started with the environment variable `GENIEACS_DEBUG_FILE` set to the path of the debug log file.
