Yes, I actually got this a few times when I tried using the PhantomBuster node before I figured out the right arguments.
This error seems to suggest there might still be data missing (or is malformatted). Which Phantom exactly are you trying to use and which settings are you using (you can blur out the actual values, I just want to see the fields you are sending)?
Hi @Ninotna, for the “LinkedIn Companies Info” phantom , have you tried setting both sessionCookie and spreadsheetUrl? Despite the name, spreadsheet URL can point to an individual company, for example https://www.linkedin.com/company/ibm/.
