Data Steam action pagination issue

[kevin33]

Good evening , All 

I running into a very weird issue on pagination. I have a API with their payload like below:

{"@odata.context": "https://abc.def.com/DEVICE_INVENTORY,0#DEVICE_INVENTORY",

"value": [

{xxxx},

{xxxx}

],

"@odata.nextLink": "https://abc.def.com/latest/DEVICE_INVENTORY?$skip=1000&$skiptoken=2,ae0a2629-891e-40d2-8cc4-183133f7..."

}

The skip number increase when page number increase.

I create pagination script as in screenshot.

Rest steps like below:

I have data source to load data, the page 1 and 2 are pretty normal, but in page 3, it report error. I check the execution steps, here is the screen shot from execution:

The nextpage link become:

https://abc.def.com/latest/DEVICE_INVENTORY?%24skip=1000&%24skiptoken=2%2Cae0a2629-891e-40d2-8cc4-183133f7fadd&$skip=1000&$skiptoken=3,ae0a2629-891e-40d2-8cc4-183133f7fadd

I have try many time from postman, and never see any response content like this. Postman response body like below:
