problem when run get-reads-alt-unmap.sh

[Huangpq2019]

When I run get-reads-alt-unmap.sh in.bam out.bam to process my data, there is an error message:

*****WARNING: Query ERR091574.99978736 is marked as paired, but its mate does not occur next to it in your BAM file. Skipping.

[bam_header_read] EOF marker is absent. The input is probably truncated.
[bwt_restore_sa] SA-BWT inconsistency: primary is not the same. Abort!
[bam_header_read] invalid BAM binary header (this is not a BAM file).
[main_samview] fail to read the header from "-".
sambamba-sort: not enough data in stream

How can I solve this problem?
