IO error on the Custom Metadata Loader page

[DownstairsB]

I've uploaded a bunch of records (which was painful enough in and of itself)...

Now When I go to add more, I get this:

IO Exception: Exceeded max size limit of 6000000 Error is in expression '{!checkMdApi}' in component apex:page in page custommetadataloader: Class.MetadataService.MetadataPort.listMetadata: line 9218, column 1 Class.MetadataUtil.checkMetadataAPIConnection: line 30, column 1 Class.CustomMetadataLoaderController.checkMdApi: line 16, column 1

An unexpected error has occurred. Your development organization has been notified.

I also got the same error, but I haven't uploaded any records before.

I got the same error, do we have any solution for this? I have deployed the required components via zip and Workbench and haven assigned respective permission set as well. Have created required remote site setting too. Kindly suggest.

I haven't found any solution so far, so disappointed.

Let me know if anyone has any leads. Thanks.

After a long time and come back to share my workaround :)

I used python to parse the each record in the csv file into custom metadata file with the format just as same as I retrieved from Salesforce using Ant Migration Tool. Then I used Ant Migration Tool to deploy these files into Salesforce. It took more than 30 minutes for the deployment since there are more than 40,000 records.

When I used these 40,000+ custom metadata by SOQL, the first call takes 10+ seconds to get any records I want, which shows that the records of custom metadata may have a very low limit.

Anyway, If you have to Upload mass custom metadata records into Salesforce, you can see my example in this repo.

I have uploaded a bunch of data into the custom metadata, while i was trying to insert a few more i got the above mentioned error. Does anyone have a solution for this?
