Goedemiddag community,

Een tijdje geleden heb ik de File upload api gebruikt in combinatie met een HTTP connector om een excel te kunnen uploaden en uitlezen. Vanwege security redenen probeer ik nu de HTTP connector uit te faseren en te vervangen met de web connection connector. Hier loop ik helaas tegen problemen aan die ik zelf niet op kan lossen.

 

Om jullie mee te nemen in het proces:

 

 

 

 

De webconnection kan worden gemaakt want de tokens worden goed uitgegeven op opgehaald:

Via postman lukt het om het excel bestand te stagen en te commiten via oath 2.0 waar ik gebruik maak van dezelfde webverbinding als in IAM staat geregisteerd.

 

De webconnection waar die fout gaat:

Chatgpt geeft aan dat het kan liggen aan de Content-Type: Waar ik in de web connection connector: ‘application/vnd.openxmlformats-officedocument.spreadsheetml.sheet’ heb staan.

Echter wordt deze nog aangepast door indicium als die uiteindelijk wordt uitgevoerd naar:

‘Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet; charset=utf-8’    (Zie 2de plaatje processflow logs:)

Waar ‘charset=utf-8’ problemen kan veroorzaken in de body door corruptie (denk aan verkeerde encoding of headers)

 

Heeft iemand hier vaker met de file api upload gewerkt voor Excel betanden via de web connection connector en tips om naar te kijken waar het probleem zit?

 

Alvast bedankt.

Mvg,
Jeffrey

Hi Jeffrey,

If the encoding is the issue, perhaps there is a way to add the desired encoding in the Web connection. In case the UTF-8 encoding is the cause of the issue, Indicium should take a look into this.

Hi Jeffrey,

This is a known issue with the web connectors: they currently do not support transferring binary data, only text.

For now, we advise continuing to use HTTP connectors for this purpose

Support for this will come soon.

Hi Erik,

Any idea when the functionality is ready to use? We need this functionality as well.

Thank you.
