I'm trying to load the metadata of a sandbox org into Intellij using illuminated cloud but the operation took too much time and fail at the end, and the following error message is displayed :
Salesforce metadata API has two limits:
- max number of metadata components in a retrieve or deploy - 10K for unmanaged and 12.5K for managed.
- max file size limit.
You are hitting this second limit. Easiest thing to do is to reduce the number of profiles in your retrieve or even better drop Documents metadata type if you are fetching it.
