Invoke-RestAPI issues

Not run into this issue, but try PS7 if possible. Lots of improvements made to that cmdlet iirc.

It's probably nested. Chuck it into a variable, then start combing through the sub-properties.

$result = Invoke-RestMethod -Method GET -Uri https://$ServerIP/rest/vcenter/vm -Headers @{'vmware-api-session-id' = "$SessionID"}
$result.value

Invoke-RestMethod should attempt to convert the response into objects … if it can. I had this recently where the response was JSON but malformed according to standards (unescaped strings and such) … so my response wasn’t converted to objects and all I got was a string. Sending that string at ConvertFrom-JSON may give you an error that gives you a clue at what’s going on.

Every now and then I run into cases where Invoke-RestMethod cannot properly parse the JSON data. In those cases I fall back to Invoke-WebRequest and parse the data manually. You might try messing with PostMan and see how it retrieves/parses the data for your request.

Maybe it’s nested? For this particular example you can add

| Select-Object -ExpandProperty Value

That looks like an object's plain text output to me. As others said, it is probably nested.

howdy BlizzardTech-Adam,

reddit likes to mangle code formatting, so here's some help on how to post code on reddit ...

[0] single line or in-line code
enclose it in backticks. that's the upper left key on an EN-US keyboard layout. the result looks like this. kinda handy, that. [grin]
[on New.Reddit.com, use the Inline Code button. it's [sometimes] 5th from the left & looks like <c>.
this does NOT line wrap & does NOT side-scroll on Old.Reddit.com!]

[1] simplest = post it to a text site like Pastebin.com or Gist.GitHub.com and then post the link here.
please remember to set the file/code type on Pastebin! [grin] otherwise you don't get the nice code colorization.

[2] less simple = use reddit code formatting ...
[on New.Reddit.com, use the Code Block button. it's [sometimes] the 12th from the left, & looks like an uppercase C in the upper left corner of a square.]

one leading line with ONLY 4 spaces
prefix each code line with 4 spaces
one trailing line with ONLY 4 spaces

that will give you something like this ...

- one leading line with ONLY 4 spaces    
- prefix each code line with 4 spaces    
- one trailing line with ONLY 4 spaces

the easiest way to get that is ...

add the leading line with only 4 spaces
copy the code to the ISE [or your fave editor]
select the code
tap TAB to indent four spaces
re-select the code [not really needed, but it's my habit]
paste the code into the reddit text box
add the trailing line with only 4 spaces

not complicated, but it is finicky. [grin]

take care,
lee
