I tried to find from the docs it seems the problem is in the "type", as below.

result of the total using **string** type

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/a/9/a938032897a6ace163d41cf9cde568a002bdbdd7.png)

result of the day using **map** type  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/9/c/9cde263e45af30a90226459580da5bb357996f90.png)

docs from tuya: [Device Data Statistic-Cloud Services API Reference-Tuya Developer](https://developer.tuya.com/en/docs/cloud/device-data-statistic?id=Ka7g7nvnad1rm)

is there a way like convert from string to map or something else.

thanks

Search the Web for `tuya cloud api "sign invalid"`

It suggests...

> Please confirm whether the signature sign is correct. Refer to the document signature mechanism:  
> [Sign Requests-Tuya IoT Development Platform-Tuya Developer](https://developer.tuya.com/en/docs/iot/open-api/api-reference/singnature?id=Ka43a5mtx1gsc)

I don't think this is relevant because it is the return value. You're not even getting a return value. You're getting a signature error.
