Hello, I have created an integration with Hubspot and I attempt to create a form when my app is installed. I just received for one of my user an error ( **400** http code) when hitting the **POST /marketing/v3/forms** endpoint: `"status":"error","message":"internal error","correlationId":"842...","category":"VALIDATION_ERROR"}` I don’t really know how to handle this error as it seems to be an internal error (I would expect a **500** ) at Hubspot but it seems that something’s wrong with some validations (the body I send has always been working until now and its content is only static values, not depening of the customer). Do I miss something? ---

Hi, @yoLotus 👋 Thanks for reaching out. Were you able to resolve this one? If not, I have a few questions to help the community better understand your issue: - Have you been able to reproduce it on your end? - Is it persistent or intermittent? - It’s only happening to one user? - If only one user, have you tried to remove or isolate other variables that could cause a [400 Bad Request](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/400) to appear? From that user? Thanks for the additional information! — Jaycee ---

Hey [@Jaycee\_Lewis](https://community.hubspot.com/t5/user/viewprofilepage/user-id/127074) sorry for the late response and thanks for your message, - I’ve only be able to reproduce with this customer, same environment - I’ve tried several times during the day and always got the same error payload - It happended only with this customer so far - Unfortunately the body of the request is always the same, whatever the customer. I’ve modified the body to make some errors on purpose (just to see) and it happened that I got a readable and usable error message. I thought the customer haven’t the right permissions to let us hit the _form_ endpoint on their behalf but they wouldn’t have been allowed to install our app beforehand. Let me know if you need more info, best regards, etienne ---

It seems that I wanted to create a Form at the customer account with a property that has been archived. As I was attempting to only install _default_ properties (basic ones as _jobtitle_, _company_…) I didn’t think it was possible to archive them (only custom ones). Nevertheless, the message is useless and should be updated ---

Actually, I was attempting to install a form with the default “phone” properties that I declared as `single_line_text` as formType. The exact value for the formType was “phone”. But once again, Hubspot api response was providing 0 clues.
