Attachment API extension file formats

[Abeer-khan]

Hello,

I'm using Rest API explorer, Attachment API ,POST (from binary request) to add few files in knowledge table. The extension file formats are config, ica, wf, reg, uda. In the System properties>Security it says to leave the extension files space empty as it will support all file formats. I did that and the error is Invalid file type: ica. Are these not supported by in Service Now? Please see the attachment. Please advise. Thank you.

Regards,

Abeer

Hi @Abeer-khan 

referring to the article https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0718013 : Is MIME type checking enabled in your instance?

Hello @Maik Skoddow,

Thanks for sharing this. MIME was enabled and it was not accepting the file formats. I disabled the MIME and all the file formats  config, nwf, reg, uda are getting accepted expect ica.
