Workflow - AxiosError 422

I have a very weird problem when adding a record to my Airtable-database
As you can see in the screenshot, all data is retrieved from my form (correctly), with 3 arrays of names (also correct).
But when executing the workflow, I get the AxiosError 422.

The strange thing is, than when I leave the field NAMEN_VD_mannen empty (unbind, so no array), the record is added correctly.
I almost tried everything I could think of, but always without result.
(all fields NAMEN_VD_mannen, NAMEN_VD_vrouwen and NAMEN_muzikanten are all similar multiselect-fields in Airtable); those fields are also used in other workflows of my project without problem)
Any idea what this “AxiosError 422” means (couldn’t find an answer on the internet)

new info : the name “Roland” (item 7 in array NAMEN_VD_mannen) gives the error :

even renaming the name to John didn’t solve the problem (then the new given name gives the AxiosError422).

Only removing this name from the main table with the names solves the problem and the record is added.
Very-very strange…

Hi Wim :waving_hand:

422 errors are returned directly from Airtable, probably this one means that you are trying to submit a structure that’s not being acccepted.

And in your error message it says “insufficient permission”.

This means that you are probably not structuring the array properly before sending it to Airtable.
