I have a fillable form that I tidied up to correct some duplicate field names, explicitly naming every field. Using the Migration tool I was able to import it as a Form. However, trying to import it as a Document fails with the error: “PDF did not validate - Error: Expected instance of t, but got instance of undefined” I searched around, but did not find any example of such an error. Thoughts? Suggestions? Thanks in advance. Dion ---

Hi @addalineappservices Can I ask what do you mean by you importing the document? ---

Hi Kenny, Sorry, wrong term. “Create Document” based on a PDF. ![image](https://canada1.discourse-cdn.com/flex030/uploads/feathery/original/1X/cc9853468c1709c1f67f284403cacc0a08c9705c.png) ---

Can you try to do this again but with your console open? Just to see more details if an error occurs. ---

Yes, the Console threw a few errors: ![image](https://canada1.discourse-cdn.com/flex030/uploads/feathery/original/1X/48a0ddcfa19120fdbd113801ce4908700205d8b7.png) The text of the errors is fairly long. Is it acceptable to save them as LOG files and post them here? Thanks, Dion ---

Hi Kenny, Can I email it directly to you? I’d prefer to keep it out of the general forum, just in case. Thanks, Dion
