For the full error reference across all platforms, see Error Reference. | Error | Explanation | Fix | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Please reduce the amount of data you're asking for, then retry your request (may also appear as "Could not upload video to Facebook: ...") | Facebook/Meta API server-side error -- not a Contouron bug. It is more common on larger Pages or groups, often around 5,000+ followers, because Facebook may run out of memory while processing the publish request. It can affect any post type (text, image, link, or video). The post can sometimes publish successfully even though the API reports a failure. | 1) Retry publishing the post -- it often succeeds on a later attempt. 2) Check the Facebook Page first to see if the post already published. 3) Wait a few minutes, then retry the post from [Failed Posts](https://my.contouron.com/failed) (web app) or re-run your automation step (n8n/Make). 4) If the post uses Page mentions, try removing the mention and adding it manually later on Facebook. 5) If the error persists across multiple retries over an hour, submit a support ticket via in-app chat with the post ID, timestamp, and Facebook Page follower count. | | Could not upload video to Facebook: (#100) The global id xxxxxxx is not allowed for this call | Your Facebook Page ID is incorrect. | Use the official Contouron n8n/Make nodes -- select the Page from a dropdown instead of copying IDs manually. See: n8n Basics. If you are passing the Page ID manually, copy it from [Settings > Social Accounts](https://my.contouron.com/settings) using the "Copy Page ID" button. | | Error posting to Facebook: (#200) requires pages\_read\_engagement and pages\_manage\_posts permission (the full message may also mention "If posting to a group..." and "requires both pages\_read\_engagement and pages\_manage\_posts as an admin with sufficient administrative permission") | Facebook Page permissions are incomplete or partially authorized, or you do not have a full Admin role on the Page. Contouron publishes to Facebook **Pages** only -- it cannot post to Facebook **Groups** or personal profiles. | 1) Go to [Settings > Social Accounts](https://my.contouron.com/settings). 2) Click Reconnect for your Facebook account. 3) In the Meta permissions popup, select "Opt in to current Pages only" and check each Page individually. 4) Confirm you have a full **Admin** role on the Page (an Editor, Advertiser, or Analyst role is not enough) -- [check your Page role](https://www.facebook.com/help/510247025775149). 5) If the Page still fails, remove the Contouron app from Meta Business Suite (Settings > Accounts > Apps) and reconnect fresh. See: Facebook Connection Guide. | | Wrong Page ID | Facebook requires both an Account ID and a Page ID. | Copy the Page ID using the "Copy Page ID" button in [Settings > Social Accounts](https://my.contouron.com/settings). Or use the official Contouron n8n/Make nodes to select the Page from a dropdown. | | Could not upload video to Facebook: There was a problem uploading your video file | The same Facebook account is connected to two different Contouron accounts. Each reconnection on one Contouron account invalidates the Facebook token on the other. | Connect each Facebook account to only ONE Contouron account. You can connect multiple Facebook accounts to a single Contouron account, but the same Facebook account cannot be linked to multiple Contouron accounts. See: Facebook Limitations. | | A message asking you to confirm or verify your identity before you can publish (the wording comes directly from Facebook) | Meta requires some Page owners to confirm their identity before the Page is allowed to publish. Facebook blocks the post until you verify, and Contouron passes Facebook's message through to you. This is a Facebook requirement, not a Contouron issue. | 1) Open the Facebook app on your phone using the account that manages the Page. 2) Find the identity confirmation prompt, usually under notifications or your Page settings. 3) Follow Facebook's steps to verify. You can also do this on desktop in Meta Business Suite under your Page's settings. 4) After Facebook confirms your identity, retry the post from [Failed Posts](https://my.contouron.com/failed) (web app) or re-run your automation step (n8n/Make). | *** **Didn't find your error?** * Full Error Reference * [API FAQs](https://github.com/Contouron-Inc/help.contouron.com/tree/main/api/faqs.md) * General FAQs --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.contouron.com/platforms/facebook/errors.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
