Hi Andreas,

I opened a case to IFS regarding this error and IFS RnD mentioned that they  have a permanent fix for this error. Below are the available fixed versions.

22.2.19 - 22R2 SU19
23.1.12 - 23R1 SU12
23.2.5 - 23R2 SU5
24.1.0 - 24R1 GA

You can refer my community post on this from below link

We have updated the environment to 24R1 but the error remains

No MediaTypeFormatter is available to read an object of type 'PdfArchiveHeader' from content with media type 'text/html'.

Hi Anders,
 

I have not yet been able to test this, as our customer, who is experiencing the same issue, has not updated their environment to the latest version.

Below is the IFS case ID that I opened earlier, which includes information about the cloud versions that would resolve the issue. If you have already opened a case, could you please reference the case ID below? If not, could you kindly open a new case and mention the following case ID?

Case ID: CS0271197
