I'm Getting an Error 500 When Submitting My Check: Causes and Requirements
The error 500 code appears when part of the submission has failed during document upload.
Before contacting support, work through the following steps.
## Check your file format and size
The document you are uploading must be:
- In PDF, PNG, or JPEG format
- Under 5MB
## Re-convert and compress your document
If your file meets the above requirements but the error persists, the issue may be caused by how the file was generated. Try the following:
1. Re-convert your document to PDF using a PDF converter or export tool
2. Compress the resulting PDF using a file compression tool before uploading
3. Re-attempt the submission
This resolves the error in most cases where format and size requirements are already met.
## Still seeing the error?
