[ERROR] Could not upsert Attachment: MetaData for ParentThe Org's metadata is stored in your Copado Org as an attachment. Whenever there are too many metadata components, you will be hitting the Salesforce filesize hard limit.
There are 2 possible ways to work this out:
1. Filter the metadata types you consider not necessary for your deployments, or split the Org Credential and many with filtered metadata.
2. Contact Salesforce Support in order to increase the file size limit.
