    Found my fault... JRahm & Patrik_Jonsson this was after my long reply to your other post JRahm (and yes it works on a POST method)... I had the file name in the URL overload specified on the initial create request, it should not be in there...

    so this..

     

     

    $File_Name = 'MyFile'
$url       = "{0}{1}{2}" -f $big_ip, "/mgmt/tm/sys/file/ifile/",$File_Name

$headers = @{
    'Content-Type'    = 'application/json'
    'X-F5-Auth-Token' = $token
}

$body = @{
    'name'            = $File_Name
    'source-path'     = "file:/var/config/rest/downloads/$File_Name"
} | ConvertTo-Json -Compress

$result = Invoke-RestMethod -Method post -Uri $url -Headers $headers -Body $body

     

     


    needs to be:

     

     

    $File_Name = 'MyFile'
$url       = "{0}{1}" -f $big_ip, "/mgmt/tm/sys/file/ifile/"

$headers = @{
    'Content-Type'    = 'application/json'
    'X-F5-Auth-Token' = $token
}

$body = @{
    'name'            = $File_Name
    'source-path'     = "file:/var/config/rest/downloads/$File_Name"
} | ConvertTo-Json -Compress

$result = Invoke-RestMethod -Method post -Uri $url -Headers $headers -Body $body

     

     

     without the file name in the initial overload.

    Hope this helps some future person 🙂 
    Off to the next challange.

    Bonus: Retyped to splat (overload definition) - because why not.

     

     

    # Create a IFile {system level} 
$File_Name = 'MyFile'
$Uri       = "{0}{1}" -f $big_ip, "/mgmt/tm/sys/file/ifile/"

# Construct overload definition
$Param_InvokeRestMethod = @{
    headers = @{
        'Content-Type'    = 'application/json'
        'X-F5-Auth-Token' = $token
    }

    body = @{
        'name'            = $File_Name
        'source-path'     = "file:/var/config/rest/downloads/$File_Name"
    } | ConvertTo-Json -Compress

    Method = 'post'

    Uri = $Uri
}

# Post & capture result
$result = Invoke-RestMethod @Param_InvokeRestMethod

Hi there!

Nice to see some Powershell users in the forum. 🙂 If you have validated that the file is actually there, try this to make sure that it's not SELinux that is tripping you up:

restorecon -RvF <file path>

Ps. Coming from Python2? Recommending string interpolation:

$url = "{0}{1}{2}" -f $big_ip, "/mgmt/tm/sys/file/ifile/", $File_Name
# Becomes
$url = "$big_ip/mgmt/tm/sys/file/ifile/$File_Name"
# A bit safer (less risk in terms of unintentionally referencing the wrong variable):
$url = "$($big_ip)/mgmt/tm/sys/file/ifile/$($File_Name)"

Also, try this for the source-path property when creating the body:

"file:/var/config/rest/downloads/$File_Name"
# instead of
"file:///var/config/rest/downloads/$File_Name"

    Thanks Patrick, ive tried both variations before typing this initial post. Saw tht in a few other examples & as with all things code if the API docs did not deliver, we are on stack overflow or forums discussing alternatives 🙂 

    using file:/// or file:/ serves up the same API 400 exit 37

     

    Invoke-RestMethod : {"code":400,"message":"Failed! exit_code (37).\n","errorStack":[],"apiError":26214401}
At line:1 char:11
+ $result = Invoke-RestMethod -Method put -Uri $url -Headers $headers - ...
+           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

     

    This is with:

     

    $File_Name = 'MyFile'
$url       = "{0}{1}{2}" -f $big_ip, "/mgmt/tm/sys/file/ifile/", $File_Name

$headers = @{
    'Content-Type'    = 'application/json'
    'X-F5-Auth-Token' = $token
}

$body = @{
    'name'            = $File_Name
    'source-path'     = "file:/var/config/rest/downloads/tmp/$File_Name"
} | ConvertTo-Json -Compress

$result = Invoke-RestMethod -Method put -Uri $url -Headers $headers -Body $body

     

    Both instances the file upload occured & exists in:

     

    remainingByteCount : 0
usedChunks         : @{0=46321}
totalByteCount     : 46321
localFilePath      : /var/config/rest/downloads/MyFile
temporaryFilePath  : /var/config/rest/downloads/tmp/MyFile
generation         : 0
lastUpdateMicros   : 1661327626220187

     


    Point taken on the string formatting,  I flip between C# & Powershell quite ofen so the formatting is more a C# habbit than Python for me.

    All of these examples are "try before writinig a function" code so these samples arent set in stone & the eventual final solution & battle tested functions & modules will be written & deployed towards the end of this excersisise 🙂 (when I get the samples working)

    Thank for your reply.
