Unfortunately, yes, you were required to upload the originals of your degrees/diplomas. In fact, you needn't have uploaded the WES ECA or the IELTS reports. I suggest you go ahead and raise a CSE asap, and include a brief LOE humbly asking the officer to attach the documents to your file. At this point, that may be all that you can do. There's a good chance that raising the CSE will do the trick. All the best.

Here's what the instructions on the document upload section (eAPR) says:
Document: Education (diplomas/degrees)
You must provide proof that you completed your post-secondary education. Examples of proof of education include a diploma and/or degree. Examples of post-secondary education are:
Trade/apprenticeship
• Training in a specific trade, such as carpentry or auto mechanics;
• Training in a profession that requires formal education but not at the university level (for example, dental technician or engineering technician); or
• Training not at the university level for which a certificate/diploma is awarded.
Bachelor’s degree
• This is an academic degree awarded by a college or university to those who completed an undergraduate curriculum (also called a baccalaureate). Example: a Bachelor of Arts, Science or Education.
Master’s degree
• This is an academic degree awarded by a graduate school of a college or university.
Ph.D.
• This is the highest university degree, usually based on at least three years of graduate studies and a thesis. Normally, you must have completed a Master’s degree before a Ph.D. can be earned."

Proof of studies
Purpose
To confirm education claims and validate that the applicant meets program requirements
Document requirements
To receive program-specific points for education, the applicant must either
provide proof of having completed a Canadian secondary or post-secondary educational program; or
obtain an Educational Credential Assessment (ECA) and provide the ECA reference number in their application, along with proof of the foreign educational credentials for which points are being claimed [emphasis mine].
Proof of completed Canadian or foreign educational credentials can include copies of
secondary or post-secondary education documents (certificates, diplomas or degrees); and
transcripts for successfully completed secondary or post-secondary studies, if available.
Where an ECA has been obtained, the applicant must provide the ECA reference number in their e-APR for online validation directly from the issuing organization.
A scanned copy of the ECA is not required when submitting the e-APR but may be requested by IRCC at a later date.
