The 'Request Entity Too Large' error typically occurs when the document being submitted exceeds the size limit that the system can process during the e-signature completion step.
This means the document file itself is likely too large. To resolve this, we would recommend reducing the file size of the document before re-uploading it as an eSign template. You can do this by compressing the PDF or reducing the resolution of any images embedded within the document, then re-uploading the smaller version as the template and resending the signature request to the employee.
If the document contains high-resolution images or was exported at a very high quality setting, try re-exporting it at a lower resolution or using a PDF compression tool to bring the file size down before uploading it into HiBob again.
Once the file size has been reduced and the document has been re-uploaded, the employee should be able to complete the signing process without encountering that error.
