 Where is the file being created? The file size limit in that data store will need to be amended. In DataVerse it is in the admin settings, so need to know the storage location to help!

Hi,

I am also facing the same issue. I'm trying to download a PowerBI report and save it in the local FTP path. But it is failing when the size is greater than 20MB. Is there any way we can get pass through this error?

 

Thanks in advance.

Hi @Dimf 

 

Kindly, help me if you got any solution for this

Chunk it and then loop through the chunks with an append to file.

Hi @NickTLS 

 

I am new to power automate

Can you help me with images on how to chunk ?

 

Requirement 

I have created a flow that will take Power BI Paginated Reports in CSV format and send to File system (SFTP location)

Here My CSV file size is around 90 MB

 

I am getting an error, size limit exceeds maximum bytes.

 

Kindly, help me. I have to get this sorted if there is any way like to zip files or any other alternative

Not sure if this is helpful but I saw this blog post today ona  similar vein:

 

Solving ‘exceeded the maximum size’ when working with images in Power Automate – Clavin's Blog (word...

SFTP Action doesn't have an "Append to File" action like File System does. However, on the UPLOAD action in your workflow go into settings. You will see a switch that says allow chunk. Play with the settings there. Start with something around 10MB and see if it will work for you. I have only don't the "Chunking" for File System stuff.

 

Here is a short blog about the "Chunk" function if you ever need it use it for File System.

Power Automate Chunk Function Explained (zeitgeistcode.com)

 

You just Chunk your file contents into sizes under 20 MB and then do an Apply to Teach on your chunk with an Append to file. My Chuck Size was set to a variable with a value of "20000000" which is 20MB in Bytes. 1 character is 1 Byte.

 

The switch action is there to see if a file with the same name already exists, if it does, start appending. I could probably have done something where if the index was 0 then create and anything else append too... but this worked for my case.
