"'request' is not defined" when uploading mezzanine

On Fernow, using V5.6.1_HQMA, importing a mezz file to a new object got the following error (see attached). When I clicked back and backed up to the mezz file level, the pdf was importing, and in the time it took to write this message and gather all the documents it completed successfully. Created object. Moved files from PD to ddrshare. Went to mezz tab, selected add file, selected file ddr-densho-478-1_mezz_redacted.pdf, verified the fields, and pushed ok or whatever. And then I got the error
