Error: options: expected array, got string - but it is an array?
I'm having trouble with an API call. It claims I send a string, but it seems to me to be an array.
This is the full error:
Error in call to API function "https://content.dropboxapi.com/2/fil...
- 4 years ago
Found the problem... the option file_categories needs to be an array as well.

Hi James_T,
Have you took a look on where parameters have to be put on? 🤔 Into header part of the HTTP query or into data part? 🧐 What are you doing actually? 🙂
Hope this tip gives right direction.

Hi,
I'm trying to do a search. I use a PHP library to handle the cURL calls. It works fine for creating a folder for instance.
Since the error is specifically about "options" parameter, I assume the call is done correctly, if it wasn't I assume I would get an error about something else, or even a missing "query" parameter?

Seems you have posted in OP your HTTP query. 🧐 Is this correct? If so, there are multiple errors! I'm guessing most of them are copy/paste errors when you prepared the post.
To be sure, what we're talking about, post exact structure of your HTTP request/response and/or the code you are using (not something like, as is posted now). Better catch your HTTP request/response, so we would be sure exactly what's going on and what's the error. 😉

Below is my complete code. And here is the result:
Error in call to API function "files/search_v2": options: expected array, got string
$token = "...."; $options = array("path" => "/", "max_results" => 10); $options["file_categories"] = "folder"; $parameters = array("query" => "searchPhrase", "options" => $options); $headers = array( "Authorization: Bearer $token", 'Content-Type: application/json' ); $curlOptions = array( CURLOPT_HTTPHEADER => $headers, CURLOPT_POST => true, CURLOPT_POSTFIELDS => json_encode($parameters), CURLOPT_RETURNTRANSFER => true, CURLOPT_VERBOSE => true, CURLOPT_SSL_VERIFYHOST => false, CURLOPT_SSL_VERIFYPEER => false ); try { $ch = curl_init('https://api.dropboxapi.com/2/files/search_v2'); curl_setopt_array($ch, $curlOptions); $response = curl_exec($ch); //var_dump($response); curl_close($ch); } catch (Exception $e) { trigger_error( sprintf( 'Curl failed with error #%d: %s', $e->getCode(), $e->getMessage() ), E_USER_ERROR ); }
Some more debugging:
echo json_encode($parameters, JSON_PRETTY_PRINT); { "query": "cat", "options": { "path": "\/folder", "max_results": 10, "file_categories": "folder" } } Error in call to API function "files/search_v2": options: expected array, got string
That sure looks like an array to me, so I don't understand why it says it's a string...
