Due to the change of the Authority address, the existing SDK package is abnormal, please upgrade to the latest version 24.5.

I have upgraded sdk to 24.5. Now I am getting 500 : Internal server error message.

I am trying to convert .xlsm file to PDF.

@seqrdocs ,
I checked your code and found that you are using the LightCellsApi, which is out of date and does not exist in the latest version.
Please refer to the code below: aspose-cells-cloud-php/Examples/Example_PutConvertWorkbook.php at master · aspose-cells-cloud/aspose-cells-cloud-php · GitHub

Okay. Thanks for support.

@seqrdocs ,
Network problems usually cause 502, and we will do further checks as soon as possible.

@wangtao ,

Today again we are facing same issue. Please check.

@wangtao , It occurs oftenly. Sometime its works and some time its not.

@seqrdocs ,
Can you provide some information about the account you are calling the API (e.g. clientId), as well as the frequency of calls to the API and the size of the file being processed, we’ll continue to look at the system logs.

@wangtao ,

Thanks for quick response.
