I encountered the same error when testing with hugo server
locally (also ~2 weeks ago, never appeared before) but got rid of it using ignoreErrors = ["error-remote-getjson"]
See below:
Local machine:
Microsoft Windows [Version 10.0.18362.1139]
Hugo version:
Hugo Static Site Generator v0.77.0-EF290125 windows/amd64 BuildDate: 2020-10-30T10:13:29Z
Is there maybe an issue with the Gitlab Hugo version not being on .77 yet and not processing the ignoreError
flag in the config.toml
?
